Question
parents are worried that their children are getting less than 8 hours of sleep due to the academic requirements . To find out if there is a reason to believe this, they took a random sample of 100 school children 16 to 22 years old and asked them about their regular number of hours of sleep per night. The mean number of hours of sleep per night of the sampled students was found to be 8.9 hours. Assuming that the distribution of the number of hours of sleep per night of the sample is normal with a standard deviation of 2.2 hours, conduct a test of hypothesis at 95% confidence interval about the true mean number of hours of sleep per night among school children 16 to 22 years old to determine if there is indeed a reason to worry.
