A student group claims that first-year students at a university must study 2.5 hours (150 minutes) per night during the school week. A skeptic suspects that they study less than that on the average. A class survey finds that the average study time claimed by 256 students is xbar = 142 minutes, with a sample standard deviation of 68. Regard these students as a random sample of all first-year students and suppose we know that the study times follow a Normal distribution. What is the standard error of the sample mean?
