Health experts say that students should get at least eight hours of sleep each night. If a random sample of 32 students at your school average 6.8 hours of sleep with a standard deviation of 2.6 hours, is there convincing evidence at the 1 percent level that the students at your school are not getting enough sleep? Provide statistical evidence to support your answer.

Sleep Time A person read that the average number of hours an adult sleeps on Friday night to Saturday morning was 7.2 hours. The researcher feels that college students do not sleep 7.2 hours on average. The researcher randomly selected 15 students and found that on average they slept 8.3 hours. The standard deviation of the sample is 1.2 hours. At α = 0.05, is there enough evidence to say that college students do not sleep 7.2 hours on average?

According to a survey conducted by the Department of Statistics Malaysia (DOSM), university students get a mean of 7 hours of sleep per night. A random sample of 50 students at IIUM revealed the mean length of time slept last night was 6 hours and 48 minutes (6.8 hours). The standard deviation of the sample was 0.9 hours. At the 5% level of significance, is it reasonable to conclude that IIUM students sleep less than the normal university students?

How much do Americans sleep each night? Based on a random sample of 1120 Americans 15 years of age or older, the mean amount of sleep per night is 8.17 hours according to the American Time Use Survey conducted by the Bureau of Labor Statistics. Assuming the population standard deviation for amount of sleep per night is 1.2 hours, construct and interpret a $95 \%$ confidence interval for the mean amount of sleep per night of Americans 15 years of age or older.
