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 X1 = 68.8 X2 = 74.7 S1 = 12.7 $2 = 8.5 n1 = 10 n2 = 14 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.)
