Which one the following statements is false about the null hypothesis?
It is the hypothesis that the observed correlation is the result of random fluctuation.
The likelihood of observing the results that we observed if this hypothesis is true, is the p-value.
It is the hypothesis that would be wrong in case our causal hypothesis is true.
The hypothesis that our causal explanation is true and explains the observed correlation.
Homework Answers
Correct option is:
The hypothesis that our causal explanation is true and explains the observed correlation.
(since null hypothesis always shows that there is no effect_)

1) In hypothesis testing, the region of rejection of the null hypothesis will always be smaller than the region of acceptance of the null hypothesis. True or False? One-sample tests use data drawn from a single sample to test that the sample comes from a specified population. True or False?
