question 4

Short Answer

Determine the Appropriate Hypothesis Test to Perform
-A random sample of 100 male employees of a retail store results in a mean monthly salary of $\$ 720$ with a standard deviation of $\$ 44$ . An independent random sample of 125 female employees of the same store results in a mean monthly salary of $\$ 705$ with a standard deviation of $\$ 25$ . Does this constitute sufficient evidence to conclude that the mean monthly salary for male employees of the store is higher than the mean monthly salary for female employees of the store? Use the $\alpha = 0.01$ level of significance.
