Question Help 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 -test are met, and use a significance level of 0.05. 15 10 Ho: before-Hafter 20 A. Ha : before-Hafter 0 Ho-before-Hafter = 0 Ho: before-Harter-o Find the test statistic. Type an integer or decimal rounded to two decimal places as needed.) Find the p-value. Type an integer or decimal rounded to three decimal places as needed.) Reject or do not reject Ho. Choose the correct answer below. O A. Reject Ho. The pulse rate increases slightly after meditation O B. Do not reject Ho. Meditation does not lower pulse rates significanty. ° C. Do not reject Ho. The pulse rate increases slightly after meditation. D. Relect Hn. Meditation lowers pulse rates significantly. Click to select your answer(s).

Explanation / Answer

The statistical software output for this problem is:

One sample T hypothesis test:
: Mean of variable
H0 : = 0
HA : > 0

Hypothesis test results:

Hence,

Hypotheses: Option F is correct.

t = 1.91

P = 0.043

Option D is correct.

Variable Sample Mean Std. Err. DF T-Stat P-value Data 3.6363636 1.9034549 10 1.9104018 0.0426
