In Fall 2022, the average GPA of Electrical Engineering (EE) majors in lower-division courses at CSUF was 2.4 and the standard deviation was 0.4. Assume that GPA's satisfy a normal distribution. Use Simpson's Rule with n = 6 to approximate the probability that a randomly selected EE student's GPA was at least a B-, (ie. between 3.0 and 4.0).
