Question 492307: A 90% confidence interval estimate for a population mean was computed to be (49.3, 67.9). Determine the mean of the sample, which was used to determine the interval estimate (show all work). Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A 90% confidence interval estimate for a population mean was computed to be (49.3, 67.9). Determine the mean of the sample, which was used to determine the interval estimate
---------------------
The sample mean is the average of the confidence interval limits:
x-bar = (67.9+49.3)/2 = 58.6
