SCENARIO 9-5
a Bank Tests the Null Hypothesis That the Mean

SCENARIO 9-5
A bank tests the null hypothesis that the mean age of the bank's mortgage holders is less than or equal
to 45 years, versus an alternative that the mean age is greater than 45 years. They take a sample and
calculate a p-value of 0.0202.
-Referring to Scenario 9-5, the bank can conclude that the mean age is greater
than 45 at a significance level of $\alpha$ = 0.01.
