3 questions

A group of eleventh graders wanted to estimate the population proportion of
students in their high school who drink at least one soda per day. Each student
selected a different random sample of 30 students and calculated the proportion
that drink at least

Describe the shape of the distribution.

What is your estimate for the proportion of all students who would report that they drink at least one soda per day?

If, instead of taking random samples of 30 students in the high school, the eleventh graders randomly selected samples of size 60, describe what will happen to the standard deviation of the sampling distribution of the sample proportions.
