The Human Resources Department believes that women tend to take more personal time than men because they tend to be the primary child care givers in the family.
-At α = 0.05,
A) we reject the alternative hypothesis.
B) we fail to reject the null hypothesis.
C) we can conclude that women take a smaller average number of hours of personal time per year compared to men.
D) we reject the null hypothesis. There is strong evidence that women take a higher average number of hours of personal time per year compared to men.
E) there is no evidence of a difference in the true average number of hours of personal time taken by women and men.
