A 95% confidence interval estimate for a population mean was computed to be (60.0 to 68.6). Determine the mean of the sample, which was used to determine the interval estimate (Please show all work)
-------------------------------
E-xbar = 60
E+xbar = 68.6
--------------------------
Subtract 1st from 2nd and solve for xbar:
2xbar = 8.6
x-bar = 4.3
