Use technology to construct the confidence intervals for the population variance o^2 and the population standard deviation o. Assume the sample is taken from a normally distributed population.
c=0.95, s^2= 20.25 n=28
The confidence interval for the population variance is (___,___) (Round to two decimal places as needed.)
The confidence interval for the population standard deviation is(___,___) (Round to two decimal places as needed.)
From the output,
The 95% confidence interval for variance is, (12.66, 37.52)
The 95% confidence interval for standard deviation is, (3.56, 6.13)
