One of your module team members, Dr Kaustubh Adhikari, conducts
research on the genetics of physical characteristics. In one such study, he
examined the height and weight data of adult participants from Peru. The
Minitab file Peru.mwx is based on the data of male and female
participants, 48 from each category. The column labelled HeightF gives the
height of female participants, while the column labelled HeightM contains
the height of male participants. Similarly, the columns labelled WeightF and
WeightM contains the weights of female and male participants respectively.
Height is measured in cm and weight in kg units. Run Minitab and open this
worksheet.
(a) Produce horizontal boxplots of the data for the heights of female and
male participants on the same diagram using Minitab. Include an
informative label for the horizontal axis as well as an informative title
for the boxplots. Include a copy of your plots in your answer.
(b) On the basis of the boxplots obtained in part (a), are the heights of
female participants left-skew, right-skew or neither? Explain your
answer.
(c) Using the two boxplots you obtained in part (a), compare the heights of
female and male participants.
