Points: 0 of 1 Consider the following data from two independent samples with equal population variances. Construct a 99% confidence interval to estimate the difference in population means. Assume the population variances are equal and that the populations are normally distributed. X = 37.8 5-8.5 n = 18 =32.4 %=9.2 n = 19 Click here to see the 1-distribution table. page 1.
