Marijuana Use During Pregnancy. For the birth weights of babies in two groups, one born of mothers who used marijuana during pregnancy and the other born of mothers who did not (see Exercise 7), the difference in sample averages (nonuser mothers minus user mothers) was 280 grams, and the standard error of the difference was 46.66 grams with 1,095 degrees of freedom. From this information, provide the following: (a) a 95% confidence interval for 12 – 41, (b) a 90% confidence interval for u2 - H1, and (c) the two-sided p-value for a test of the hypothesis that u2 - 41 = 0.
