In a statistics class, students took their pulses before and after being frightened. The frightening event was having the teacher scream and run from one side of the
room to the other. The pulse rates (beats per minute) of the women before and after the scream were obtained separately and are shown in the accompanying table.
Treat this as though it were a random sample of female community college students. Test the hypothesis that the mean of college women's pulse rates is higher after
a fright, using a significance level of 0.05.
Click the icon to view the table of pulse rates before and after the scream.
Assume that the sample was random and that the distribution of differences is sufficiently Normal. Mention the level of significance.
a = 0.05 (Type an integer or a decimal. Do not round.)
Step 3: Compute to compare
Find the test statistic for this test.
t = - 6.52 (Round to two decimal places as needed.)
Find the p-value for this test.
p-value = 0.000 (Round to three decimal places as needed.)
Step 4: Interpret
Reject or do not reject Ho. Then write a sentence that includes "significant" or "significantly" in it. Report the sample mean pulse rate before the scream and the
sample mean pulse rate after the scream.
Reject
Ho. The sample mean before the scream was
beats per minute and the sample mean after was
beats per minute. College women's pulse
