When estimating a population meanwith a confidence intervalestimate, then E is:
A) equal to the level of confidence.
B) one-half the width of the confidence interval.
C) a multiple of the population mean.
D) a multiple of the population standard deviation.
When we calculate a confidence interval we first find an estimate of the population mean. We estimate the population mean with the sample mean, which is …
The solution examines confidence intervals for estimates.
