A graduate-level computer science course only gives the grades of A, B, or C. The department has determined that there should be 40% A's given, 40% B's given and 20% C's given as final grades for the course. For the spring 2021 semester, 200 students took the course and 100 students received A's, 50 students received B's and 50 students received C's, so those are my observed frequencies. We want to do a Chi-square Multinomial Goodness of Fit test to see if our grading guidelines match up with what is actually happening. What is the expected frequency for the grade of B category? Round your answer to the tenths position.
