You may need to use the appropriate appendix table or technology to answer this question. Consider the following results for two samples randomly taken from two populations. Sample A Sample B Sample Size 27 29 Sample Mean 27 24 Sample Standard Deviation 8 7 (a) Determine the degrees of freedom for the t-distribution. (Round your answer down to the nearest integer.) 64 X (b) Develop a 95% confidence interval for the difference between the two population means. (Use Sample A - Sample B. Round your answer to three decimal places.) to (c) Is there conclusive evidence that one population has a larger mean? Explain. Because the range of the interval is from negative to positive, it indicates that there is conclusive evidence (at 95% confidence) that Sample A has a larger mean than Sample B. Because the range of the interval is from positive to positive, it indicates that there is no conclusive evidence (at 95% confidence) that Sample A has a larger mean than Sample B. O Because the range of the interval is from positive to positive, it indicates that there is conclusive evidence (at 95% confidence) that Sample A has a larger mean than Sample B. Because the range of the interval is from negative to positive, it indicates that there is no conclusive evidence (at 95% confidence) that Sample has a larger mean than Sample B.
