As in the previous problem, 64 students are randomly selected from a statistics class. If X is the number of students who received a B or above on the final exam, then the distribution of X can be approximated with a normal distribution, N (32, 4.0), where the mean (u) is 32 and standard deviation () is 4.0. Using this approximation, find the probability of 36, 37, or 38 students receiving a B or above on the final exam. You may use the portion of the Standard Normal Table below.
