A random sample of 27 observations is used to estimate thepopulation variance. The sample mean and sample standard deviationare calculated as 44 and 4.5, respectively. Assume that thepopulation is normally distributed. (You may find it useful toreference the appropriate table: chi-square table or F table)
a. Construct the 95% interval estimate for the populationvariance. (Round intermediate calculations to at least 4 decimalplaces and final answers to 2 decimal places.)
b. Construct the 99% interval estimate for the populationvariance. (Round intermediate calculations to at least 4 decimalplaces and final answers to 2 decimal places.)
