A researcher is interested in testing how listening to music affects exercise performance. She has one group listen to Tool and another group listen to Jonas Brothers. The number of consecutive reps on the bench before stopping was being measured. The following data was collected:

Listening to Tool: 15, 18, 16, 19, 20

Listening to Jonas Brothers: 10, 9, 11, 13

a. What are the null and research hypotheses?

b. Determine the values necessary to calculate the t statistic:

Mean of X:

Mean of Y:

standard error:

c. What is the t statistic?

d. Determine the critical value using a two-tailed hypothesis test at a 0.05 significance level

e. Make a decision about the hypothesis

Independent samples t-test: An experimenter is interested in how the “foot-in-the-door” tactic could increase compliance in college students. The “foot-in-the-door” tactic involves asking first for a small request to butter someone up for a larger (originally intended) request. Typically, the “foot-in-the-door” tactic increases compliance because people do not like to appear inconsistent and since they originally agreed to the small request, they feel compelled to also agree with the large request. Our experimenter was seeking to increase the number of...
