True or False Outcomes of hypothesis testing if you reject H

True or False

Outcomes of hypothesis testing: if you reject Ho then you know the null hypothesis was definitely false in the population

Solution

False. You cannot be definitely sure the null hypothesis was false in the population because you still have the chance of committing a Type I error, which is rejecting the null when it is in fact true. The probability of committing this error is equal to the alpha level of the test.
