Question

A polling firm wants to predict the success of a grocery store, and conducts surveys of randomly selected residents. The residents are asked whether they will shop for produce at the grocery store. The results are shown in the table. The actual percent of residents who will shop for produce at the grocery store is expected to be furthest away from which number?1)37.5%2)50.0%3)61.9%4)56.0%

Answer 1

The smaller the sample size, the greater the uncertainty in our estimate.

From the options, 37.5% is obtained from the smallest sample size (8) and thus the percent is expected to be furthest away from this value.

Answer: 37.5%.
