Consider the following data for two independent random samples taken from two normal populations. Excel File: data 10-11.xlsx T2 Sample 1 Sample 2 a. Compute the two sample means. (to nearest whole number) A T = 1 = 10 7 13 7 9 8 8 7 8 4 69 b. Compute the two sample standard deviations. (to 2 decimals) $1 = 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) ) Hint(s) Check My Work
