A manufacturer of mosquito repellent claims that the average amount of time that its repellent is effective is at least 3.5 hr. A consumer group tests the claim using five randomly selected people. If the average time of effectiveness from the sample was 3.8 hr with a standard deviation of 0.76 hr, what is the critical value (CV), test statistic (TS), and decision for this test? (Useα= 0.025.)

CV = –2.7764; TS = 0.88; fail to rejectH0


CV = 2.7764; TS = 0.88; fail to rejectH0


CV = 2.5706; TS = 0.39; fail to rejectH0


CV = –2.5706; TS = –0.88; fail to rejectH0
