a) Find Figure 2(d). Give approximate values for the mean and standard error of the mean for each of the two groups. State whether "mean" here refers to the sample mean or to the true mean. Give an interpretation of the standard error of the mean for the long nap group, in the context of the problem at hand. (This is still referring to the variable illustrated in Figure 2(d).) b) Consider again Figure 2(d). In that plot, they report a p-value of 0. 17. What test procedure did they use? Give the hypotheses of the test corresponding to that p-value, in words and symbols, and give an appropriate conclusion that relates to the variables under study. Do not use the phrases 'reject Ho' or 'do not reject Ho' at any point in your response. (You may speak in terms of statistical significance, or strength of evidence, just not in terms of rejecting the null or not.)
