Eleven students took their pulses while in class. Then they were asked to meditate by sitting with their eyes closed and counting their breaths for 5 minutes. After this, they took their pulse rates again. The data recorded provide differences: pulse before meditation minus pulse after meditation. So a negative value means that the pulse rates increased after meditation. Treat these students as a random sample of college students and perform a hypothesis test to determine whether the mean pulse rate decreased after meditation. In other words, determine whether the mean difference is positive. Assume that the conditions for using a t-test are met, and use a significance level of 0.05.

Mean = 3.0909Sd = 7.2451Df = 11 – 1 = 10 = ( 3.0909 – 0 ) / 7.2451 / sqrt(11)= 0.1286For this t score The two-tailed P value equals 0.9002
