Answer:
a. at least 20%, when in fact, it is less than 20%.
Step-by-step explanation:
Type 1 Error is to reject null hypothesis when it is actually true.
Here the null hypothesis is fewer than 20% of Evergreen Valley College (EVC) students attended the show.
In mathematics fewer than 20% means less than 20%.
So the null hypothesis is that less than 20 % students attended the show.
We have to reject this hypothesis .
We can reject this hypothesis when we assume that the % is greater than or equal to 20 %
At least 20% means greater than or equal to 20%.
So the best choice is option a.
at least 20%, when in fact, it is less than 20%.
