The mean work week for engineers in a start-up company is believed to be about 60 hours, on average. A newly hired engineer hopes that it’s shorter. She asks ten engineering friends in start-ups for the lengths of their mean work weeks. The sample average was 58.1 hours and the standard deviation was 3.4 hours. Should she count on the mean work week to be shorter than 60 hours? Conduct a hypothesis test at the 5% significance level. Show all steps
