You may need to use the appropriate appendix table or technology to answer this question. The following results come from two independent random samples taken of two populations. Sample 1 Sample 2 n = 50 na = 35 *1 = 13.6 x2 = 11.6 5. = 2.3 02 = 3 (a) What is the point estimate of the difference between the two population means? (Use 7; -7z.) (b) Provide a 90% confidence interval for the difference between the two population means. (Use X1 - z. Round your answers to two decimal places.) (c) Provide a 95% confidence interval for the difference between the two population means. (Use xq - Xz. Round your answers to two decimal places.) Need Help? Watch It Master It 2.

HW2 > 0 The following results are for two independent samples taken from the two populations. Sample 1 Sample 2 n = 40 n2 = 50 *1 = 25.7 x2 = 22.8 0 = 5.4 (a) What is the value of the test statistic? (Round your answer to two decimal places.) (b) What is the p-value? (Round your answer to four decimal places.) (c) with a = 0.05, what is your hypothesis testing conclusion? O Do not Reject Ho. There is sufficient evidence to conclude that - M2 > 0. O Reject Ho. There is insufficient evidence to conclude that M1 - My >0. Reject Ho. There is sufficient evidence to conclude that H1 - H2 > 0. Do not reject Ho. There is insufficient evidence to conclude that My - 42 > 0.
