If a researcher chooses a confidence level greater than the 95%, which of the following will occur?

A) a smaller confidence interval that contains the population mean
B) a larger confidence interval that contain the population mean
C) a loss of precision in estimating the sample mean
D) a loss of precision in estimating the population mean

Confidence Level

The confidence level is a measure of the reliability of an estimate or interval, expressed as a percentage, indicating how often the true parameter falls within the estimated range in repeated samples.

Confidence Interval

A range of values, derived from sample statistics, that is likely to contain the true value of an unknown population parameter.

Population Mean

The average of all the values in a population, representing a central point around which the values of the population are distributed.
