Consider the following data for two independent random samples taken from two normal populations. Excel File: data10-11.xlsx Sample 1 10 7 13 7 9 8 Sample 2 ৪ 7 8 4 6 9 a. Compute the two sample means. (to nearest whole number) T1 = T2 = b. Compute the two sample standard deviations. (to 2 decimals) S1 = 82 = c. What is the point estimate of the difference between the two population means? d. What is the 90% confidence interval estimate of the difference between the two population means? (to 2 decimals and enter negative value as negative number)
