In an experiment, students were given words to memorize, then were randomly assigned to either take a 90 minute nap or take a caffeine pill. A couple hours later, they were tested on their recall ability. We wish to 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. a). What are the null and alternative hypotheses for this test?b). If the results of the test comparing sleep and caffeine for memory are statistically significant, what does that mean in terms of sleep, caffeine, and memory?c). If the results are not statistically significant, what does that mean in terms of sleep, caffeine, and memory?
