A national survey claims that adults take at least 20 minutes on average to get ready in the morning. Using the survey results, conduct a hypothesis test for this claim at the α = 0.05 significance level. Then construct an appropriate confidence interval for the mean preparation time and use it to verify whether your hypothesis-test conclusion is consistent. Survey Results “Estimate: How long does it take you (in minutes) to get ready in the morning? ” 20 30 min 90 min 15 10 minutes It typically takes me about a half an hour to get ready in the morning 15 40 30 15 45 minutes 20 35 30 30 25 30 28 90 30 2 hours 15 minutes 25 I’m not exactly sure of what ‘to get ready in the morning’ entails…I haven’t had a job in a few years now, but not very long.
