Question

I report if u guess or answer randomly. 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.
54%
B.
61%
C.
38%
D.
26%

Answer 1

B. 61%

Explanation:

The higher the level of confidence you want, the larger you must make the interval to give you that high confidence the population mean will lie within it.

Of the numbers listed, a confidence level of 61% is the highest, so will give the widest interval.
