The Department of Management Science at Tech has sampled 250 of its majors and compiled the following frequency distribution of grade point averages (on a 4.0 scale) for the previous semester. GPA Frequency 0-0.5 1 0.5-1.0 4 1.0-1.5 20 1.5-2.0 35 2.0-2.5 67 2.5-3.0 58 3.0-3.5 47 3.5-4.0 18 250 for this distribution is 2.5 and the sample standard deviation (s) is X 0.72. Determine if the student GPAs are normally distributed using a .05 level of significance (i.e. a = .05).I need the excel formulas with solution
