Question

Answer these two questions (repost bc last answer was wrong):

Suppose that 60% of the students at your school favor a proposed school policy that would ban cell phones at school. Also suppose that every student in your class selected a different random sample of 50 students from your school and calculated the proportion of students in the sample who favors the ban.

5. If your class constructed a dot plot of all these sample proportions, where would you expect the dot plot to be centered?

6. If every student had selected a random sample of size 25 instead of a sample of size 50, would you expect a dot plot of the sample proportions to be more spread out or less spread out than in a dot plot of sample proportions for samples of size 50?
