Assume that X, the starting salary offer for sociology majors, is normally distributed with a mean of $43,256 and a standard deviation of $3,150. The probability that a randomly selected sociology major received a starting salary offer less than $48,600 is? 0.4554 0.9554 0.0446 0.70 The probability that a randomly selected sociology major received a starting salary offer between $42,000 and $48,600 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.) What percentage of sociology majors received a starting offer between $36,000 and $42,000? 66.61% 97.13% 2.87% 33.39%
