Answer to Problem 24E

The correct option is (e)

Explanation of Solution

Given:

There are two sample sizes 500 and 1000.

The width of the confidence interval is negatively related to the sample size and increase in sample size increases the precision of the confidence interval which reduces the risk of being correct.

Here, if sample size 1000 is used at the same confidence level of 95% then the confidence interval would be lower and there would be same risk of being incorrect.

Hence, the correct option is (e)
