The information below is based on independent random samples taken from two normally distributed populations having equal variances. Based on the sample Information, determine the 98% confidence interval estimate for the difference between the two population means. n = 13 n2 = 16 X4 = 60 X2 = 56 S16 $25 C The 98% confidence interval is (11-12) (Round to two decimal places as needed.)
The paired samples shown in the accompanying table have been obtained from normally distributed populations. Construct a 95% confidence interval estimate for the mean paired difference between the two population means. Click the icon to view the data table. Let wo--Hy. Construct a 95% confidence interval estimate for the mean paired difference between the two population means. (Round to four decimal places as needed.)
