Students wanted to see whether exercising (in particular doing jumping jacks) would help or hinder people’s ability to memorize a list of 10 words that were read to them. This would be compared to the same test of memorizing words while the subjects were sitting down. The number of words memorized for the 31 subjects can be found in the data file ExerciseMemorize.
a. What is the explanatory and what is the response variable in this study?
b. Write down the hypotheses in either words or symbols.
c. Put the data into the Matched Pairs applet. What is the value of the statistic that will be used in the study and what does it represent.
d. Randomize at least 1,000 times to develop a null distribution and determine a p-value.

e. Is there strong evidence that exercising while trying to memorize a list of words helps or hinders the process?
