What are the degrees of freedom for this contingency test? Step 1: For a tiny data table like this, it is quite easy to just create the data by hand. First by creating a vector by reading the top row, the middle row, and then the last row. Then we can tell R that the data should be shaped as a 3 x 3 matrix. Open RStudio and execute the following code: c c(2, 4, 20, 8, 9, 1, 7, 9, 7) ; observed matrix(c, 3, 3, byrowtrue) ; print The observations were print(observed Step 2: Recall that the next step in a contingency test is calculating what we would expect. The null is that the treatment variable (quantity of oyster shells) is independent of the response variable (claw type).

"Differential reflex activity determines claw and where closer muscle asymmetry in developing lobsters." Science 233 (1986 354-357.). Problem 1 The two claws of juvenile lobsters are identical. By adulthood, however, typically the two claws have differentiated into a stout claw called a crusher and a slender claw called a cutter. A research team wanted to determine the effect of the environment on the differentiation process. They took juvenile lobsters and placed them in one of three experimental treatments: 26 were reared in smooth plastic trays, 18 were reared in trays with many oyster chips (i.e. Broken shells) which allowed the animals to exercise their claws, and 23 were reared in trays with only one oyster chip. The claw configurations of individual lobsters were then scored as adults: crusherR, cutterL crusherL, cutterR, both cutters. No chips 2 4 20, oyster chips 8 9 1 1 Oyster chip 7 9 7, did the rearing environment affect the development of the lobster claws? Question 1: State the null and alternative hypotheses. Question 2: What is the expected number of animals with two cutter claws in the smooth plastic treatment if the null hypothesis is true?

The chi-square contingency test is an important way to evaluate whether two variables are independent thank of each other. The simplest case is a table. The test can be extended, however, to any number of rows and columns. As usual, we will assume alpha.05 for all tests. For situations with only two variables and two outcomes per variable, we can also use the odds ratio to summarize the magnitude of the association between the variables. Lets consider an actual study (govind,. K., and joanne pearce.

Ladies and gentlemen, my government, nasa, which many of us in the United States say stands for never a straight Answer, proceeded to erase 40 rolls of film of the Apollo Program — the flight to the moon, the flight around the moon, the landings. They erased, for Christs sake, 40 rolls of film of those events. Now were talking about several thousand individual frames that were taken that the so-called authorities determined that you did not have a right to see. Oh, they were disruptive, socially unacceptable, politically unacceptable.

Brandenburg was also the deputy manager of the Clementine mission to the moon, which was part of a joint space project between the ballistic Missile defence Organization (bmdo) and nasa. The mission discovered water at the moons poles in 1994. Source: page 16 of 18 source source according to Brandenburg, and his team of scientists/colleagues who have also published multiple papers with and alongside him concerning the subject, Analysis of recent Mars isotopic, gamma ray, and imaging data supports the hypothesis that perhaps two immense. Analysis rules out large unstable natural nuclear reactors, instead, data is consistent with mixed fusion-fission explosions. Imagery at the radioactive centres of the explosions shows no craters, consistent with airbursts. Explosions appear correlated as the site of an ancient planetary nuclear massacre, must now be considered.

Brandenburg identified isotopes with a weapons signature and showed the nuclear data, he claims it happened on the northern region of Mars. Here is a lecture by him explaining his findings. The above" is taken from the abstract of t his paper they published, and have presented multiple times. As with any other scientist, no matter how reputable, credible and accomplished, the instant you put out data and information that goes against the grain or has the ability to basically change peoples worldview paradigm, its instantly ridiculed and shut down, no matter how strong. That being said, all of this is happening for a reason, and more and more information like this will continue to emerge which has is questioning what we think we know. Ive written about Mars, in-depth, multiple times, and its a planet with no shortage of mysterious, and perhaps fibs, as we never really seem to be told the truth about anything. The thing is, if Mars was an Earth-like planet, was there intelligent life on it billions of years ago?

The ratio between the amount of hydrogen and help deuterium on Earth gives a baseline to compare rations on other terrestrial ing the appropriately na, es Very large telescope (VLT) and the keck telescope, the researchers charted the abundance of H20 and hdo over the mars. This then enabled them to map out the deuterium/hydrogen (D/H) ration mapped across the how of Mars. This is great, but neither study knows exactly what happened on Mars to cause such a dramatic climate shift, what would cause an Earth-like planet to become what Mars has come today. Researchers hypothesize that it could have been a massive climatic shift, but there is no evidence to support that theory. One physicist has come forth with some actual evidence to support his theory, and thats. Hes well-known for working on space plasma technologies, nuclear fusion and advanced space propulsion.

What Happened On Mars? Mars is the planet most like earth(and in the past mars was a very different planet, it had an extensive atmosphere, and in fact, it had what we believe was a huge ocean, perhaps as large as two thirds the northern Hemisphere. And that ocean may have been as much as a mile deep. So keywords mars indeed three billion years ago had extensive water resources. Mars suffered a major climate change and lost its surface water. james Green, nasa director of planetary sciences. ( source one of the studies liked above, attempts to chart where mars lost the most water, which was done by tracking the water molecule (H2o and its deuterated equivalent hdo. According to, ifl, deuterium is heavy hydrogen, an isotope of our lightest element with an extra neutron in its centre. It exists in our own ocean, where about.0156 of the hydrogen atoms in water are actually their heavier counterpart.

Astrophysics, told npr. You can access the entire Italian study here. Many old, as well as several recently published results,  have presented very strong evidence yet that there used to be much more water on Mars. In fact, in 2015, nasa held a press conference to announce the major discovery that the planet Mars experienced a massive climate shift in the past, that it actually used to be very earth-like, covered in oceans and greenery. You can view that entire conference here. Mars is not the dry, arid planet that we thought of in the past(and) liquid water has been found on Mars james Green, nasa director of planetary sciences. At this conference, scientists also stated that the possibility of life in the interior of Mars has always been very high. Theres certainly water somewhere in the crust of MarsIts very likely, i think, that there is life somewhere in the crust of Mars. What caused The massive climate Shift?

We see it everywhere in all subjects, especially in science, where the human race tends to hold on to what it thinks it knows while ridiculing a new discovery, only until it takes its place as fact within the mainstream. Quantum physics is a great example thats definitely challenging paperless the accepted framework of knowledge and academia, especially with its connection to consciousness and non-material science overall, in general. You can read more about the recent events surrounding ufo disclosure below: The us government Just Admitted to recovering Materials From ufos here Are The latest Updates. The same goes for planetary sciences, although we think we know a lot about our world and other planets, there is still so much to discover, and still a lot of information thats changing every single year which forces us to go back and re-write. A great example is Mars, and science is now showing that Mars wasnt always and isnt the dry, red, arid planet weve all been told it is, this theory was amplified recently by a team of Italian scientists, who are telling the world that they. The more we observe mars, the more information were getting that it really is a fascinating planet, from the curiosity rover we now know that Mars once was like a planet very much life earth, with long salty seas, with fresh water lakes, probably with. Right now, within mainstream planetary science, the debate and speculation of whether there was once life on Mars are huge, and this has sparked the debate once again since, from our level of understanding, we believe that liquid water is an essential ingredient for life. The evidence cited by the Italian study came from an instrument called marsis, which sits aboard the european Space Agencys (ESA) Mars Express spacecraft in orbit around the red Planet. Marsis is a special kind of radar called ground-penetrating radar.

The facts: Scientists have been publishing papers, this latest one out of Italy, showing how there is liquid water on Mars, as well as the fact that Mars essay used to be a very earth-like planet that might have harboured intelligent life. Reflect On: Why does any reputable renowned scientist who comes forward with evidence get vilified by the mainstream? Why are these questions and evidence regarding extraterrestrial life not answered? Why does science and evidence that defy belief get ignored? We are going to mars, our journey to mars is a science led expedition right now, but soon I hope well be sending humans to the red planet to explore and science will lead the way. And todays announcement of a really fascinating result about current water on Mars is one of the reasons why i feel its even more imperative that we send astrobiologists and plantary scientists to mars to explore the question of, is there current life on Mars? john Grunsfeld, five time space flown astronaut, Associate Administrator, head of nasa science mission Directive ( source history is written by the victors, and today, information that makes its way into the mainstream is carefully considered before being put out there. We are currently seeing this happen with ufo disclosure and other topics that dont really fit within the framework of accepted knowledge.

Asked whether a certain np complete problem could be solved in quadratic or linear time10 The precise statement of the pnp problem was introduced in 1971 by Stephen cook in his seminal paper "The complexity of theorem proving. It's a fascinating story, go look. We are going to follow in John Snow's footsteps to learn about testing hypotheses.
