A study is trying to determine if teens get more sleep per night than adults, on average. A research group conduted a study, with the following sample results: Teens: =9.4 hours, s,=2.1 hours, n=15. Adults: a=8.1 hours, s,=3.2 hours, n=20. Perform a hypothesis test to determine if this is strong evidence that teens get more sleep than adults, on average. What is the P-value? Round your answer to 3 decimal places. Do not type a percentage or a percent symbol. Use a = 5%. What are your conclusions? O Reject H, and accept HA. We have strong evidence that the mean amount of sleep that teens get is more than the mean amount adults get. O Accept Ho. We have strong evidence that the mean amount of sleep that adults get is more than the mean amount teens get. O Fail to reject Họ. We do not have strong evidence that the mean amount of sleep that teens get is more than the mean amount adults get.
