Data from a sample of randomly selected students is shown below. The variables collected are:
Exercise - the number of hours a student exercise per week
Debt - the amount of student loan debt (in thousands of dollars) a student is expected to graduate with
Age - the age of a student
GPA - the GPA of a student
A 95% confidence interval for the population variance of the student ages was calculated to be (2.14, 10.17).
You are asked if you believe if the population variance of the student ages is 2. How do you respond?
Group of answer choices
We are 95% confident that the population variance of all student ages is equal to 2.
We are 95% confident that the population variance of all student ages is greater than 2.
We are 95% confident that the population variance of all student ages is less than 2.
At the 95% confidence level, the population variance of all student ages might be 2.
