You can put this solution on YOUR website! A 99% confidence interval estimate for a population mean was computed to be (36.4 to 51.6). Determine the mean of the sample, which was used to determine the interval estimate (show all
------------------------------------
x-bar + E = 51.6
x-bar - E = 36.4
----------------------
Add to get:
2(x-bar) = 88
x-bar = 44 (this is the sample mean)
