K O Points: 0 of 1 Save Consider the following data from two independent samples with equal population variances. Construct a 90% confidence interval to estimate the difference in population means. Assume the population variances are equal and that the populations are normally distributed. X = 36.8 S = 8.5 n = 18 X2 = 32.9 $2 = 9.1 n2 = 19 Click here to see the t-distribution table, page 1 Click here to see the t-distribution table, page 2 The 90% confidence interval is (.). (Round to two decimal places as needed.)
