The state of CT claims that the average time on death row is 15 years. A random survey of 75 death row inmates revealed that the average length of time on death row is 17 years with a standard deviation of 6.9 years. Conduct a hypothesis to test the state of CT's claim. What type of test should be run? z-test of a proportion t-test of a mean The alternative hypothesis indicates a left-tailed test two-tailed test right-tailed test Calculate the p-value. What is the decision? We fail to reject the claim that the average time on death row is 15 years We reject the claim that the average time on death row is 15 years
