In the dataset linked below, some physical and performance data from a random sample of 243 weightlifters have been collected. The variables recorded for each subject are listed below.
Variable Description
id Subject ID
gender Either "Male" or "Female"
bodyweight The weight of the subject
age Age of subject in years
weightlifted The maximum weight lifted by the subject in a specific exercise [not specified]

The data set (whose first 5 records are shown below) can be found on iLearn under Resources in the file:

ID gender bodyweight age weightlifted
subj1 Male 111.7 32.6 176.9
subj2 Female 85.2 17.8 116.6
subj3 Female 82.5 30.0 115.5
subj4 Female 88.2 28.2 116.2
subj5 Male 129.2 27.0 189.8
Import the data in a Minitab worksheet following the instructions below:
(a) Choose File > Open Worksheet.
(b) If you are using a PC, select the correct file type from the list that is located above the Open button.
(c) Browse to the csv file and select it.
(d) Click Open.
Check that the imported data are the same as in the table above. Please note, the data have been generated and are in no way related to any real data set. The goal of this assignment is to use the methods learnt in the unit (please don’t use other methods) and write a statistical report which addresses the following research questions:
(a) Is there any difference in the average age of male and female weightlifters?
(b) What is the relation between the body weight of weightlifters and the maximum weight they can lift?
In the first question you have to check if the distribution of age has the same mean for males and females. In order to do this, you have to check the assumptions and in particular that the two samples could come from normal distributions with equal variances. In the second question we want to study the relation, if any, between the body weight of weightlifters and the maximum weight they can lift. In this case you have to take care of the role of the gender: can you study males and females together, or do you have to split the data set and make two regressions?
