First, a hypothesis statement and assumption are made about the population parameter or probability distribution. This initial statement is called the Null Hypothesis and is denoted by Ho. An ...

Hypothesis testing begins with a statement, known as the null hypothesis. The statement is typically one which says that there is “nothing” special going on, and that “no” dramatic action is called ...

Example of Hypothesis Testing If a researcher wants to test if a penny is fair, the null hypothesis would state that the probability of landing on heads is exactly 50%. The alternative hypothesis ...

It then remains possible that in future samples, null results can occur with a probability > .95 without overturning the falsity of that hypothesis.

Confusing these two is equivalent to mixing up “given that someone is Catholic, what is the probability that they are the Pope?” and “given that someone is the Pope, what is the probability that they ...

And again, an important characteristic of hypothesis testing is that statisticians can only attach a probability about being wrong if they reject the null hypothesis.

Beta risk is the probability that a false null hypothesis will be accepted by a statistical test.
