A manufacturer of mosquito repellent claims that the average amount of time that its repellent is effective is 3.8 hr. A consumer group tests the claim using five randomly selected people. Perform a hypothesis test to see if the average time of effectiveness is less than 3.8 hr. If the average time of effectiveness from the sample was 3.5 hr with a standard deviation of 0.76 hr, what is the critical value (CV), test statistic (TS), and decision for this test, and list HO? (Use Q = -0.025)
