You can put this solution on YOUR website! You are given the following information, find the Z-statistic: (95% level of confidence) based on the Z-test
Xbar = 980
U = 1000
Sample stdev = 50
N = 36
-------------------------------
The z-value depends only on the level of confidence.
For 95% confidence the z-value is 1.96
