A StatCrunch survey was done asking what percentage of liquid intake was in the form of soda. Figure A shows the output given.
a. Figure B is a histogram of the percentage for the females. Describe the shape of the distribution of the sample, and comment on whether it would be better to compare means or medians and explain why.
b. Descriptively compare the percentage of liquid intake that was soda for men and the percentage for women. Who consumes the larger percent age of soda?
c. Assuming we have a random sample of StatCrunch users, test the hypothesis that the medians are not equal, using a significance level of 0.05.
