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. If you wanted to test this claim,
what type of statistical test would you do and why?
