A university investigation was conducted to determine whether women and men complete medical school in significantly different amounts of time, on the average. Two independent random samples were selected and the following summary information concerning times to completion of medical school computed. Perform the appropriate test of hypothesis, at level 0.05 to determine whether there is a significant difference in time to completion of medical school between women and men.

Women Men
Sample Size 90 100
Mean 8.4 years 8.5 years
Standard Deviation 0.6 years 0.5 years

Group of answer choices

A) Since the p-value of the test is 0.2150, there is enough evidence to conclude that there is a significant difference in mean time to completion of medical school between men and women.

B) Since the p-value of the test is 0.8572, there is not enough evidence to conclude that there is a significant difference in mean time to completion of medical school between men and women.

C) Since the p-value of the test is 0.2150, there is not enough evidence to conclude that there is a significant difference in mean time to completion of medical school between men and women.

D) Since the p-value of the test is 0.1075, there is enough evidence to conclude that there is a significant difference in mean time to completion of medical school between men and women.

E) Since the p-value of the test is 0.8572, there is enough evidence to conclude that there is a significant difference in mean time to completion of medical school between men and women.

F) Since the p-value of the test is 0.1075, there is not enough evidence to conclude that there is a significant difference in mean time to completion of medical school between men and women.
