Which of the following is a Type I​ error?

Mathematics
1 answer:
Sedaia [141]2 years ago
3 0
Answer:

C. The president rejects the hypothesis that the proportion of students who earn a​ bachelor's degree within six years is 0.398​, ​when, in​ fact, the proportion is 0.398.

Step-by-step explanation:

A type I error occurs if you reject the null hypothesis when it is true.

Now the hypotheses are:

H_0: The proportion is 0.398

H_1: The proportion is less than 0.398

If in actual fact the proportion is 0.398, then the president must not reject the H_0.

This is a correct decision.

If in actual fact the proportion is 0.398, and the president rejects the H_0, then a type I error is committed.

The correct choice is C.
