The waiting time for patients at local walkin health clinic

The waiting time for patients at local walk-in health clinic follows a normal distribution with a mean of 15 minutes. The quality-assurance department found in a sample of 50 patients that the mean waiting time was 14.25 minutes. At the 0.05 level, is the mean waiting time less than 15 minutes? The p-value is 0.0446. What is your conclusion regarding this hypothesis.

Reject the null hypothesis since the p-value is less than 0.05.

Reject the alternate hypothesis since the p-value is less than 0.05.

Do not reject the alternate hypothesis since the p-value is less than 0.05

Do not reject the null hypothesis since the p-value is less than 0.05

Solution

As

p = 0.0446 < 0.05, then WE REJECT THE NULL HYPOTHESIS. [OPTION A]
