Bjork Larsen was trying to decide whether to use a new racing wax for cross-country skis. He decided that the wax would be worth the price if he could average less than 55 seconds on a course he knew well, so he planned to test the wax by racing on the course 8 times. His 8 race times were: 56.3, 65.9, 50.5, 52.4, 46.5, 57.8, 52.5, 43.2 Should he buy the wax? Perform an appropriate hypothesis test and state your conclusion, in context.
