Suppose a math professor that teaches differential calculus has found that the average course grade over the years (pre-COVID) has been 73.8. During the COVID lockdowns, this calculus professor taught a differential calculus class remotely that had 124 students whose course grades averaged 78.9 with a sample standard deviation of 11.1. Is this an unusually high course grade? Use a = 0.05.
