To explain: The effect of increase in confidence level on the confidence level.

Expert Solution & Answer

Answer to Problem 8PT3

The confidence interval would be wider and less precise.

Explanation of Solution

Given:

Confidence level = 95%

Confidence interval = (1010, 1321)

The increase in confidence level leads the increase in width of the confidence interval and provides the less precision about the population parameter.

So, if the 98% confidence interval instead of 95% is used then the confidence interval would be wider and interval would be more precise because there would be more possibility for the population mean.

The correct option is (a).
