## [answered] Assume that you want to construct a 95% confidence interval

Assume that you want to construct a?95% confidence interval estimate of a population mean. Find an estimate of the sample size needed to obtain the specified margin of error for the?95% confidence interval. The sample standard deviation is given below.Margin of error equals=\$77,standard deviation equals=\$2424

The required sample size is _____. (Round up to the nearest whole number as?needed.)

Sample Size for 95% CI, E = 77 and ? = 2424

Confidence level = 95% and Desired Margin of Error, E = 77.

Minimum sample size is given by:

x

???

E

P (|?

x ? ?| &lt; E) ? 1 ? ? ? P (...
