Question

The middle interval around the population proportion which captures 95% of sample proportions of vehicles that exceed the speed limit is:

0.792 0.848

	What was the sample size to build this interval
a	621
b	654
c	688
d	724

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
