You may need to use the appropriate appendix table or technology to answer this question. Consider the following data for two independent random samples taken from two normal populations. Sample 1 10 14 6 9 8 Sample 2 8 (a) Compute the two sample means. Sample 1 9 Sample 2 7 (b) Compute the two sample standard deviations. (Round your answers to two decimal places.) Sample 1 2.83 Sample 2 1.79 (c) What is the point estimate of the difference between the two population means? (Use Sample 1 - Sample 2.) 2 (d) What is the 90% confidence interval estimate of the difference between the two population means? (Use Sample 1 - Sample 2. Round your answers to two decimal places.) 0.54 X to 4.24 X
