Question

question 6 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. 11%
d. 54%

Explanation:

The width of a confidence interval for a population mean depends on the confidence level. A higher confidence level requires a larger critical value (e.g., z-score or t-score), which increases the margin of error and thus the interval width. Among the options, 54% is the highest confidence level.

Answer:

D. 54%
