Use the appropriate tests to find out if there are any differences in size between male and female Wits students. State your reason for using the tests chosen. [Assume that the data comes from populations that are normally distributed]

Ho: u(M) = u(F)
Ha: u(M) ≠ u(F) (claim)
= -.65368
Degree of Freedom is 38
p-value = 2*P(t> -.65368 when df = 38) = 2*tcdf(-.65368,100,38) = 2(.2586)= .5172
Since the p-value is greater than 5%, fail to reject Ho.
Conclusion: No significant Difference in size between male and female Wits students according to this study
