Answer :

To find the confidence interval, we need to calculate the mean and the standard deviation of the sample. In this case, the 94% confidence interval for the population variance is 85.8 to 130.

The student is given a list of numbers, which represents a confidence interval for the population variance. To find the confidence interval, we need to calculate the mean and the standard deviation of the sample. Then we use these values to calculate the lower and upper bounds of the confidence interval.

In this case, the lower bound of the confidence interval is 85.8 and the upper bound is 130. Therefore, we can be 94% confident that the population variance falls within this range.

To find the confidence interval, we need to calculate the mean and the standard deviation of the sample. In this case, the 94% confidence interval for the population variance is 85.8 to 130.
