Question

Which of the following would be a correct interpretation of a​ 99% confidence interval such as 4.1 less than muless than​5.6? Choose the correct answer below. A. We are​ 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu. B. It means that​ 99% of sample means fall between 4.1 and 5.6. C. It means that​ 99% of all data values are between 4.1 and 5.6. D. There is a​ 99% chance that mu will fall between 4.1 and 5.6.

Answer 1

Answer: A.  We are​ 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.

Step-by-step explanation:

The correct interpretation of a 99% confidence interval is that we are 99% confident that the true population mean falls in it.

Given  99% confidence interval : $4.1<\mu<5.6$

Then, the correct interpretation :  We are​ 99% confident that the interval from 4.1 to 5.6 actually does contain the true value of mu.
