98% confidence interval estimate for a population mean was computed to be (45.9, 60.5). Determine the mean of the sample, which was used to determine the interval estimate
-----
Equations:
x-bar-E = 45.9
x-bar+E = 60.5
-------
Add to get:
2(x-bar) = 106.4
----
x-bar = 53.2
==================
Notice that x-bar is the average of 45.9 and 60.5.
====================
