Question
How do I find the point estimate s^2? I was wondering about the formula used for excel as well.
You randomly select and measure the contents of 10 bottles of cough syrup. The results (in fluid ounces) are as follows: 4.212, 4.294, 4.254, 4.245, 4.186, 4.226, 4.268, 4.243, 4.229, 4.231.

Assume the sample is taken from a normally distributed population. Construct 95% confidence intervals for (a) the population variance \( \sigma^2 \) and (b) the population standard deviation \( \sigma \). Interpret the results.

(a) The confidence interval for the population variance is \( ( \, \, ) \).
(Round to six decimal places as needed.)

[Note: As this is a transcription task, specific numerical answers are not provided for the confidence intervals.]
