stats questions help attached, show work needed for some questions.

A. The statement does not make sense because the bias is due to the small sample size and not the proportion of males and females sampled.

B. The statement does make sense because the movie going population does not have anywhere near the disproportionate number of men to women as is present in the sample.

C. The statement does make sense because a sample of movie goers will always be more representative than a sample that includes the general male and female population.
