assume the mean annual salary for graduates 10 years after graduation is $124,000. Assume the standard deviation is $34,000. Suppose you take a simple random sample of 14 graduates. Round all answers to four decimal places if necessary. a. What is the distribution of X? X-N 124000 34000 o b. What is the distribution of I? T - N 124000 184.39 o o 9086.8822 c. For a single randomly selected graduate, find the probability that her salary is between $125,370 and $136,913. 0.1318 o d. For a simple random sample of 14 graduates, find the probability that the average salary is between $125,370 and $136,913
