Suppose the mean pulse rate of college students is 68 beats per minute with a standard deviation of 11.5. You conduct a special exercise program for 31 college students. After completing the program, the mean pulse rate of the students was 64.1.Test the hypothesis that the program lowered students' pulse rates using a = 0.01.
there is sufficient evident to... View the full answer
- Sorry I used α =0.05, instead of α=0.01 but here is the correction: =>critical value Zα =Z0.01 =-12.33 Since -1.888 > --2.33, we fail to reject Ho and conclude that there is insufficient evident to support that the program lowered students' pulse rates
