Problem 4, the following data were collected as part of a study of coffee consumption among male and female undergraduate students. The following reflects cups per day consumed.
Male::: 3 4 6 8 2 1 0 2
Female: 5 3 1 2 0 4 3 1
----------------------------
Differ::-2,1,5,6,2,-3,-3,1
-------------------------------
sample mean of the differences: 0.875
std of the differences::::::::: 3.44
------------------------------------------
Margin of Error: (invT(0.975,7)*3.44/sqrt(8) = 2.3646*1.2162 = 2.8759
---
Generate a 95% confidence interval for the difference in mean numbers of cups of coffee consumed between men and woman
95% CI: 0.875-2.8759 < u(diff) < 0.875+2.8759
