Question 1168611
4 js correct
5 is correct-it is the non-rejection of a false null hypothesis.

1. It is Ho: mu=22. The parameter of interest is the length of the prison sentence, not the sample size. To compare with Florida, assume Cal's is the same in the null hypothesis (all H1 choices are irrelevant).  It is b.

2. Given Ho, a two-way test, the critical value is |z|>1.96, or e. You are correct.

3. 5 is within the CI, which is another way of saying that 5 is a plausible value, meaning fail to reject Ho. When the CI fails to contain a value, one can assume that value is not plausible given the constraints.
