Question
Suppose Michigan State University's Collegiate Employment Institute found that starting salaries for recipients of bachelor's degrees in business was $50,032 in 2017. The results for a sample of 100 business majors receiving a bachelor's degree in 2018 showed a mean starting salary of $51,277 with a sample standard deviation of $5,200. Conduct a hypothesis test to determine whether the mean starting salary for business majors in 2018 is greater than the mean starting salary in 2017. Use ? = 0.01 as the level of significance.
State the null and alternative hypotheses. (Enter != for ≠ as needed.)
H0:
Ha:
Find the value of the test statistic. (Round your answer to three decimal places.) =
Find the p-value. (Round your answer to four decimal places.)
p-value =
State your conclusion.
(A) Reject H0. There is sufficient evidence to conclude that the mean starting salary for business majors has increased in 2018.
(B) Do not reject H0. There is sufficient evidence to conclude that the mean starting salary for business majors has increased in 2018.
(C) Do not reject H0. There is insufficient evidence to conclude that the mean starting salary for business majors has increased in 2018.
(D) Reject H0. There is insufficient evidence to conclude that the mean starting salary for business majors has increased in 2018.
