The paper referenced in the previous exercise also compared the reported heights and weights to actual measured heights and weights for a sample of 1052 female college students selected from eight different universities. The resulting data are summarized in the accompanying table. You can assume that this sample is representative of female college students.?

a. Carry out a hypothesis test to determine if there is a significance difference in the mean reported weight and the mean actual weight for female college students.

b. Carry out a hypothesis test to determine if there is a significance difference in the mean reported height and the mean actual height for female college students.

c. Do the conclusions reached in the hypothesis tests of Parts (a) and (b) support the conclusion that female college students tend to under-report both height and weight? Explain.
