SCENARIO: A final year Biostatistics student is interested in exploring University student's lifestyle habits. Data pertaining to twenty-nine (29) students were collected for this investigation. Figure 1 details a section of the instrument used to collect the data. Table 1 illustrates the related codebook used for some of the responses. Table 2 provides the coded responses for the twenty-nine (29) students.

This new variable should be formed in order to satisfy the criteria in table 3. Produce a frequency distribution for this new variable ensuring that the appropriate labels are included. Table 3 - Particulars for new variable Weight_Classes Weight 80 3 = Students weight above 80kg Task 6: For the data variables Weight_Classes and Exercise, use the Crosstabs option to: a) produce a cross-tabulation summarizing the data; b) determine whether the weight classes are associated with level of exercise by using an appropriate test at a 1% level of significance. Ensure that the hypotheses for the test are stated. SCENARIO: A final year Biostatistics student is interested in exploring University student's lifestyle habits.
