Question

In 2018, the mean age of a prisoner on death row was 40.7 years. A psychologist wondered whether the mean age of a prisoner has changed since then. He randomly selects 33 prisoners and finds that their mean age is 38.9 with a standard deviation of 9.6. Use an α = 0.05 level of significance. Determine the word(s) that make the statements true. a. The value of z0 [ Select ] ["is", "", "", "is not"] in a critical region. b. We [ Select ] ["reject", "do not reject"] H0. c. This was a [ Select ] ["right", "left", "two"] -tailed test. d. There is/are [ Select ] ["one", "two"] critical region(s) in the associated standard normal distribution. e. The sample evidence [ Select ] ["does not", "does"] suggest that the mean age of a prisoner has changed since 2018. f. This was a question testing a hypothesis regarding a population [ Select ] ["mean", "proportion"] . Previous
