Question 900283
Ho: u(M) = u(F) 
Ha: u(M) ≠ u(F) (claim)

{{{ t =(61.4211-62.2857)/sqrt(14.1462/19+ 21.1143/21) }}}= -.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
