To compute the minimum sample size for an interval estimate of μ, we must first determine all of the following except
A) desired margin of error.
B) confidence level.
C) population standard deviation.
D) degrees of freedom.

Question

Quizplus · Accepted Answer

Degrees of freedom are not required for computing the minimum sample size for an interval estimate of μ. The necessary inputs are the desired margin of error, confidence level, and either the population standard deviation or an estimate of it from a previous sample.
