In an experiment, students were given words to memorize, then were randomly assigned to take a 90 minute nap or take a caffeine pill. They were then tested on their recall ability. We test to see if the sample provides evidence that there is a difference in mean number of words people can recall depending on whether they take a nap or have some caffeine. The hypotheses are: Ho: Ps= Pc VS Ha: sc. The sample statistic is sc = 3.0. Use the randomization distribution to find the p-value.

In an experiment, students were given words to memorize, then were randomly assigned to take a
90 minute nap or take a caffeine pill. They were then tested on their recall ability. We test to see if
the sample provides evidence that there is a difference in mean number of words people can recall
depending on whether they take a nap or have some caffeine. The hypotheses are:
Ho : μs = με
The sample statistic is sc = 3.0. Use the randomization distribution to find the p-value.
