The average starting salary for an MBA graduate in the class of 2018 was $112,000. Assume the population standard deviation for starting MBA salaries was $19,000. A random sample of 30 MBA graduates from the class of 2018 was selected.
a. What is the probability that the sample mean is less than $119,000?
b. What is the probability that the sample mean is more than $105,000?
c. What is the probability that the sample mean is between $112,000 and $119,000?
d. Suppose the sample mean was $115,500. Does this result support the average starting salary findings?
