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 95% confidence interval estimate for the difference between the two population means. ny = 19 X1 = 54 S1 = 6 n2 = 11 x2 = 56 S2 = 5 The 95% confidence interval is s(41-42) (Round to two decimal places as needed.)
Expert Answer
n1 = 19; x1 = 54; s1 = 6 n2 = 11; x2 = 56; s2 = 5 t-distribution for 95% confidence level = 2.05 df1 = 19 - 1 = 18 df2 = n
