For each of the questions below, test the hypotheses using the critical value method and the p-value method. Several retired bicycle racers are coaching a large group of young prospects. They randomly select seven of their riders to take part in a test of the effectiveness of a new dietary supplement that is supposed to increase strength and stamina. Each of the seven riders does a time trial on the same course. Then they all take the dietary supplement for 4 weeks. All other aspects of their training program remain as they were prior to the time trial. At the end of the 4 weeks, these riders do another time trial on the same course. Test at the 2.5% significance level whether taking this dietary supplement results in faster times in the time trials. Use a test statistic (₂) of 1.983.
