1. Assume the average speed of a serve in women's tennis is around 118 mph, with a standard deviation of 12 mph. We recruit 26 amateur tennis players to use our method. After 6 months we calculate a group mean of 123 mph. Perform the 5 steps of hypothesis testing necessary to determine whether the average speed of serve in women's tennis is different than that of amateur players. perform the 5Steps of Hypothesis using a 95% Confidence Level. You should write out each step; be sure to interpret the results.
