That is, by trying to prove the hypothesis was not true!

Traditional testing (the type you probably came across in elementary stats or AP stats) is called Non-Bayesian. It is how often an outcome happens over repeated runs of the experiment. It’s an objective view of whether an experiment is repeatable.
Bayesian hypothesis testing is a subjective view of the same thing. It takes into account how much faith you have in your results. In other words, would you wager money on the outcome of your experiment?

: In everyday language, an error is simply a mistake, but in science, error has a precise statistical meaning. An error is the difference between a measurement and the true value, often resulting from taking a . For example, imagine that you want to know if corn plants produce more massive ears when grown with a new fertilizer, and so you weigh ears of corn from those plants. You take the mass of your sample of 50 ears of corn and calculate an average. That average is a good estimate of what you are really interested in: the average mass of ears of corn that could be grown with this fertilizer. Your estimate is not a mistake — but it does have an error (in the statistical sense of the word) since your estimate is not the true value. Sampling error of the sort described above is inherent whenever a smaller sample is taken to represent a larger entity. Another sort of error results from systematic biases in measurement (e.g., if your scale were calibrated improperly, all of your measurements would be off). Systematic error biases measurements in a particular direction and can be more difficult to quantify than sampling error.

I’m stuck on how to value the null or alternative hypotheses

Galetto,  (2014)[abstract:] "We show a proof of the so-called Riemann Hypothesis.

One of the most important ways in which the rock record supports evolutionary theory is the succession of fossils in older versus newer rock layers. As far back as the 18th century, scholars realized that fossils in older layers differed more from modern life forms than fossils in newer layers. While many fossils from the Pleistocene Ice Age resemble organisms living today, far fewer fossils from the Age of Reptiles do. If you venture back in the rock record to the Precambrian (prior to roughly 550 million years ago), you'll find few fossils of multicellular organisms at all, though you will find some. So striking has this fossil succession been that when asked what would disprove evolution, 20th-century British scientist J.B.S. Haldane quipped, "Fossil rabbits in the Precambrian." No such bunnies have ever been found.

An example of poetic gibberish: "Each autonomous individualemerges holographically within egoless ontological consciousness as anon-dimensional geometric point within the transcendental thought-wavematrix."

What role do human beings play in this hypothesis.

Try to come up with your own examples of poorthinking, and figure out what the error(s) were.

Emotionally Driven Hypothesis The ways in which we attempt to determine the history of early man say much more about who we are today, and who we will be tomorrow, and who we want to be today, and who we want to be tomorrow, than they do about who we were in the past.

One argument raised about the fossil record is that it has no transitional forms. Yet two of the earliest, most famous fossils ever found were stunning examples of transitional fossils. In 1860, the limestone quarry in Solnhofen, Germany, yielded a fossil feather. A year later, the same quarry gave up a better prize: a partial skeleton of . , in all fairness a brilliant comparative anatomist, described the fossil as "unequivocally a bird" and suggested that, if the whole creature were found, it would look like a modern bird. It certainly wouldn't have any teeth. In 1877, a complete specimen was found at Solnhofen, and this fossil sported a toothy grin to refute Owen's prediction. It was a lizard- and bird-like fossil.

This is smaller than our alpha value of .05. That means we should reject the null hypothesis.

Next, you’ll need to state the null hypothesis (See: ). That’s what will happen if the researcher is wrong. In the above example, if the researcher is wrong then the recovery time is less than or equal to 8.2 weeks. In math, that’s:
H0 μ ≤ 8.2
