Find the critical values xß and xî for the given confidence level c and sample size n. c= 0.90, n = 15 = XÅ (Round to three decimal places as needed.) x (Round to three decimal places as needed.)
Use technology to construct the confidence intervals for the population variance o? and the population standard deviation o. Assume the sample is taken from a normally distributed population. c=0.99, s= 6.25, n = 25 The confidence interval for the population variance is (D). (Round to two decimal places as needed.) The confidence interval for the population standard deviation is (OO). (Round to two decimal places as needed.)
