Ski University would like to advertize their quality ski instructors by estimating the population mean number of lesson hours it takes for adult learn-to-ski participants to "graduate" from their program, that is, to ski comfortably on their own. A random sample of 27 recent adult learn-to-ski participants at Ski University was obtained, and each was asked to report the amount of lesson hours they took to graduate. As a result of the study a 98% confidence interval was found to go from 2.4 lesson hours to 4.6 lesson hours.
