Question

A student was asked to find a 90% confidence interval for the proportion of students who take notes using data from a random sample of size n = 84. Which of the following is a correct interpretation of the interval 0.1 < p < 0.31? Check all that are correct. With 90% confidence, a randomly selected student takes notes in a proportion of their classes that is between 0.1 and 0.31. There is a 90% chance that the proportion of notetakers in a sample of 84 students will be between 0.1 and 0.31. With 90% confidence, the proportion of all students who take notes is between 0.1 and 0.31. There is a 90% chance that the proportion of the population is between 0.1 and 0.31. The proprtion of all students who take notes is between 0.1 and 0.31, 90% of the time.

correct answers are:

1)With 90% confidence, a randomly selected student takes notes in a proportion of their classes that is between 0.1 and 0.31

3)With 90% confidence, the proportion of all students who take notes is between 0.1 and 0.31.

5 )The proportion of all students who take notes is between 0.1 and 0.31, 90% of the time.
