a) display the data with a side - by - side bar chart.
b) display the data with a segmented bar graph.
c) based on your investigation, would you agree or disagree that there is an association between a persons sex and their interest in the super bowl?

Explanation:

Step1: Analyze side - by - side bar chart

In the side - by - side bar chart, for the "Game" category, the number of males (279) is much higher than females (200). For "Commercials", females (156) outnumber males (81). For "Won't Watch", the numbers are relatively closer.

Step2: Analyze segmented bar graph

In the segmented bar graph, the proportion of males and females within each category (Game, Commercials, Won't Watch) can be seen. The differences in proportions are evident.

Step3: Determine association

Based on the visual differences in both the side - by - side bar chart and the segmented bar graph, the distribution of interest (Game, Commercials, Won't Watch) varies between males and females. So, there is an association.

Answer:

Agree
