1 . Two randomly selected groups of students were given an assessment to quantify their ability to think logically and problem solve. The summary statistics for the two groups is provided below. Mathematics Majors Computer Science Majors XM = 84.1 Xcs = 81.7 SM = 9.1 SCM = 4.6 nM = 28 ncs = 31 a. Find the 90% confidence interval of the true difference in means. Provide the form your interval takes, along with the values required for this level of confidence. b. Interpret the meaning of the interval you calculated in part a. Additionally, state whether the value zero is captured in your interval or not and what this implies
