Question

question 20 of 25
which confidence level would produce the widest interval when estimating
the mean of a population from the mean and standard deviation of a sample
of that population?
a. 26%
b. 38%
c. 61%
d. 54%

Explanation:

Step1: Recall the relationship between confidence level and interval width

A higher confidence level requires a larger critical value. A larger critical value leads to a wider confidence interval.

Step2: Compare the given confidence levels

Among \(26\%\), \(38\%\), \(54\%\), and \(61\%\), we need to find the highest value.

Answer:

C. 61%
