Use technology to construct the confidence intervals for the population variance sigma squared and the population standard deviation sigma . Assume the sample is taken from a normally distributed population.
cequals 0.95, sequals 38, nequals 20
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.)
The statistical software output for this problem is:
Hence,
95% confidence interval for population variance = (835.13, 3080.44)
95% confidence interval for population standard deviation = = (28.90, 55.50)
