In this exercise involving paired differences, consider that it is reasonable to assume the populations being compared have approximately the same shape and that the distribution of paired differences is approximately symmetric. A sample of 10 men was used in a study to test the effects of a relaxant on the time required to fall asleep. Suppose data for 10 subjects showing the number of minutes required to fall asleep with and without the relaxant follow. Subject 1 2 3 4 5 6 7 8 9 10 Relaxant No Yes 14 12 9 23 11 8 10 6 9 7 11 11 9 4 9 7 14 11 10 5 Use a 0.05 level of significance to determine whether the relaxant reduces the median time required to fall asleep.
