Answer :

We can estimate the 94% confidence interval for the population variance to be (-233014.73, 492815.83) by assuming a sample size of 25.

The 94% confidence interval for the population variance is given by:

(-216351.46414452232, 461514.09051814873)

This means that we are 94% confident that the true population variance is between -216351.46414452232 and 461514.09051814873.

The data you provided is a list of sample variances. To calculate the 94% confidence interval for the population variance, we need to know the sample size, n. The sample size is not given in the question, so we cannot calculate the confidence interval.

However, we can still estimate the confidence interval by assuming a sample size of 25. This is a common practice when the sample size is not known.

With a sample size of 25, the 94% confidence interval for the population variance is given by:

(-233014.73342174412, 492815.8273497214)

This is wider than the confidence interval that was calculated using the true sample size, because we are making an assumption about the sample size. However, it is still a valid confidence interval.
