ssume that X, tandard deviation of $3,150. the starting salary offer for sociology majors, is normally distributed with a mean of $43,256 and a Use the following Distributions tool to help you answer the questions. (Note: To begin, click on the button in the lower left hand corner of the tool that displays the distribution and a single orange line.) Standard Normal Distribution Mean 0.0 Standard Deviation-1.0 -4 -3 -2

The probability that a randomly selected sociology major received a starting salary offer greater than $42,000 is 0.6554 The probability that a randomly selected sociology major received a starting salary offer between $42,000 and $48,600 is 0.6108 (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? ) 33.39% 2.87% 66.61% 97.13% Twenty percent of sociology majors were offered a starting salary greater than $43,754.96
