A type two error is characterized as failing to reject the null hypothesis when it is wrong.

02

Explanation

Calculates the probability that a test will get the proper result for a valid alternative hypothesis that has been accepted.

b. Do not rejectH0: There is not sufficient evidence to conclude that less than 30%of teen girls smoke to stay thin.

c. Do not reject H0: There is not sufficient evidence to conclude that more than 30% of teen girls smoke to stay thin.
