Assume that X, the starting salary offer for anthropology majors, is normally distributed with a mean of $39,269 and a standard deviation of $2,550. The probability that a randomly selected anthropology major received a starting salary offer less than $38,000 is
The probability that a randomly selected anthropology major received a starting salary offer between $38,000 and $41,950 is
(Hint: The standard normal distribution is perfectly symmetrical about the mean, the area under the curve to the left (and right) of the mean is 0.5. Therefore, the area under the curve between the mean and a z-score is computed by subtracting the area to the left (or right) of the z-score from 0.5.)
