The following data represent the number of times students at a certain university read the newspaper each week. Complete parts a through d below using the Comparing Two Means app. Be sure to use the data in this exercise and not the preloaded data when using the web app. Females: Males: 7,0,2,7,6,14,1,7,5,5,1,7,7,4,5,3,0,4,2,2,6,1,3,2,3,4,3,3,2,5,4 5,7,5,2,6,4,6,3,1,3,2,7,5,4,2,11,6,3,3,1,5,0,4,14,3,7,7,3,2 .... OB: The distribution of responses for females is skewed to the right. The distribution of responses for males is approximately normal. 00 OC. The distribution of responses for females and males are very similar and both are approximately normal. D. The distribution of responses for females and males are very similar and both are skewed to the right, but the populations may not be too far from normal. b. Construct and interpret a 95% confidence interval comparing population means for females (HF) and males (HM). The 95% confidence interval for (HF-HM) is from to (Round to two decimal places as needed.)
