Short Answer

Expert verified

Hence there is no association between gender and opinion for this sample .

Step by step solution

01

Part (a) - Step 1 : Given Information - Survey includes1152 adults and we need to calculate their percentage weightage in order to draw the bar graph .

Part (a) - Explanation : We calculate percentage weightages after which we see their affect as a gender on the given data . After calculating data we derive a conclusion.


MaleFemale
Strongly Agree76/516=14.73%
59/636=9.28%
Agree270/516=52.33%
247/636=38.84%
Neither agree nor disagree87/516=16.86%
139/636=21.86%
Disagree61/516=11.82%
184/636=28.93%
Strongly disagree22/516=4.26%
90/636=14.15%

02

Part (b) - Step 2 : Given - We now need to derive and think of the association .

Explanation : No, there is no association between gender and opinion but the data for women has wide range of dispersion . Over two-thirds of men agree or strongly agree with this statement, compared to slightly less than half of the women. The percentages who disagree or strongly disagree tell a similar story is 16%of men versus 30%of women.
