Conduct an independent samples t-test using the following data:
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

A researcher is also a fan of mixed martial arts (MMA) and helps
run an MMA gym in his spare time. He decides to see which striking
style is most effective and trains his fighters in one of three
styles, then records the amount of significant strikes the fighters
land in their next fights. The data is as shown:

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...
