Use hypothesis testing in the following problem to determine whether the null hypothesis is correct.

n = 100

mean = 46

standard deviation = 12

Null hypothesis M = 50

Alternate M does not = 50

use a confidence level of 95%

The mean (46) is not in the expected critical region (47.648 to 52.352) so the null hypothesis is proven wrong.
