Use a 95% level of confidence in your hypothesis tests. A collegiate long jumper is hoping to improve his distance with improved conditioning. His new conditioning routine should help him be able to jump further than he has in the past. Before the conditioning began, the jumper was averaging 24.5 feet. After his new routine was finished, he jumps a series of 30 jumps over the course of a week. A histogram of this sample data from the 30 jumps is approximately normal with an average of 25.0 feet and a standard deviation of 1.6 feet. Does this new sample give evidence that he has actually increased his average jumping distance? Construct an appropriate Hypothesis Test to answer this question.
