A certain statistics instructor participates in triathlons. The accompanying table lists times (in minutes and seconds) he recorded while riding a bicycle for five laps through each mile of a 3-mile loop. Use a 0.05 significance level to test the claim that it takes the same time to ride each of the miles. Does one of the miles appear to have a hill? Click the icon to view the data table of the riding times. Determine the null and alternative hypotheses. Ho: H₁: Riding Times (minutes and seconds) Mile 1 Mile 2 Mile 3 3:15 3:23 3:24 3:22 3:20 3:22 3:21 3:16 3:18 3:19 3:33 3:30 3:28 3:30 3:28 T (Note: when pasting the data into your technology, each mile row will have separate columns for each minute and second entry. You will need to convert each minute/second entry into seconds only.) X
