(Round to two decimal places as needed.)

What does the confidence interval tell about the population of all college students in the state? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice.

We are confident that

of all students gave evaluation ratings between

nothing

and

nothing

(Round to one decimal place as needed.)

We are

confident that the interval from

nothing

actually contains the true mean evaluation rating.

(Round to one decimal place as needed.)

The results tell nothing about the population of all college students in the state, since the sample is from only one university.
