[MAKE TWO SCATTERPLOTS OF THE DATA, ADD A TRENDLINE (with “display equation on chart” and
“display R-squared value on chart”) AND DO TWO CORRELATION TESTS ON THE DATA SORTED BY
GENDER]

3. Are there any differences in the percentage of males and the percentage of females in each of the four BMI
categories? [MAKE A BAR GRAPH OF THE NUMBER OF MALES AND FEMALES IN EACH CATEGORY AND
MAKE A VISUAL COMPARISON]. Compare your answer to the conclusion for Question 1 and comment if they
match or if they contradict each other.
