Suppose I want to know if being a man or woman in America predicted a particular outcome, such as whether people got a flu vaccine last year. So I select a random sample of 200 college undergraduates (100 men, 100 women) from around the country and ask them if they received a flu vaccine last year. Sixty percent of the men in my sample reported getting a flu vaccine last year, whereas 80% of the women said they had received a flu vaccine last year. Please answer the following questions based on this study. . Do you think the sample is a good representation of the population? Explain your answer.

. Do you think the sample is a good representation of the population? Explain your answer.
Sample size is
In sample, 60% is the sample proportion of flu vaccine of men.
In sample, 80% is the sample proportion of flu vaccine of women.
These sample proportions estimate the proportion in the population for men and women, respectively.
