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 null hypothesis would be rejected at a significance level of  = 0.05.

Quizplus · Accepted Answer

The p-value of 0.0202 is less than the significance level of 0.05, meaning that there is strong evidence against the null hypothesis. Therefore, the null hypothesis would be rejected at a significance level of 0.05. The p-value (0.0202) is less than the significance level of 0.05, indicating that we have enough evidence to reject the null hypothesis. Therefore, the null hypothesis would be rejected at a significance level of 0.05.
