The dean of a business school wants to conduct a hypothesis test to determine whether the mean starting salary of graduates of her school is greater than $50,000. Which of the following descriptions would represent a Type Il error? 500 a) The dean fails to reject the null hypothesis and concludes that there is not enough evidence to support the claim that the mean starting salary of graduates of her school is greater than $50,000, but, in fact, the mean starting salary of graduates of her school is greater than $50,000. b. The dean fails to reject the null hypothesis and concludes that there is not enough evidence to support the claim that the mean starting salary of graduates of her school is greater than $50,000, but, in fact, the mean starting salary of graduates of her school is not greater than $50,000. c. The dean rejects the null hypothesis and concludes that there is enough evidence to support the claim that the mean starting salary of graduates of her school is greater than $50,000, but, in fact, the mean starting salary of graduates of her school is greater than $50,000. d. The dean rejects the null hypothesis and concludes that there is enough evidence to support the claim that the mean starting salary of graduates of her school is greater than $50,000, but, in fact, the mean starting salary of graduates of her school is not greater than $50,000. e. It is impossible to make a Type Il error in this situation
