Chi-Square/Contingency Table Analysis

Professor Johnson who is a professor at Yale’s University and wanted to see if his grade distribution after his first year of teaching was comparable to the overall university grade distribution, which has the following percentages: A = 10%, B = 22%. C = 40%, D = 21% and F = 7%. The distribution of Professor Johnson grades for 323 students at the end of his year was a follow: 38 students received As, 78 received Bs, 139 received Cs and 55 received Ds, and 13 received Fs. Does Professor Johnson grade distribution fit the overall college’s distribution? Test, using apla = 0.05.
