Student study times. Exercise 16.19 (page 389) describes a class survey in which students claimed to study an average of ¯ x = 13.7 hours in a typical week. Regard these students as an SRS from the population of all undergraduate students at this university. Does the study give good evidence that students claim to study more than 13 hours per week on the average? State null and alternative hypotheses in terms of the mean study time in hours for the population. What is the value of the test statistic z? What is the P-value of the test? Can you conclude that students do claim to study more than 13 hours per week on the average?
