Question

question 10 of 10
which confidence level would produce the widest interval when estimating
the mean of a population based on the mean and standard deviation of a
sample of that population?
a. 42%
b. 57%
c. 69%
d. 83%

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 the values \(42\%\), \(57\%\), \(69\%\), and \(83\%\), we need to find the largest one.

Answer:

D. \(83\%\)
