Answer:
If we reject null hypothesis that means at most 20% when in fact, it is more than 20%.
Step-by-step explanation:
Consider the provided information.
A statistics instructor believes that more than 20% of Evergreen Valley College (EVC) students attended the opening midnight showing of the latest Harry Potter movie. She surveys 84 of her students and finds that 11 attended the midnight showing.
It is given that Type I error is to conclude.
We reject null hypothesis when p value is less than α.
Type I error occurs when we reject null hypothesis but actually the null hypothesis was true.
Therefore, If we reject null hypothesis that means at most 20% when in fact, it is more than 20%.
