You may need to use the appropriate technology to answer this question. A client wants to determine whether there is a significant difference in the time required to complete a program evaluation with the three different methods that are in common use. Suppose the times (in hours) required for each of 18 evaluators to conduct a program evaluation follow Method 1 Method 2 Method 3 66 64 56 72 71 65 67 77 69 78 66 55 75 74 59 74 70 64 Use a = 0.05 and test to see whether there is a significant difference in the time required by the three methods. State the null and alternative hypotheses. O Ho: Not all populations of times are identical. Mo: All populations of times are identical. Ho: All populations of times are identical. Mo: Not all populations of times are identical. Ho: Median, - Median, * Mediang Mo: Median, - Median, - Mediany Ho: Median, - Median, - Median My: Median, > Median, > Medianz Ho: Median, - Median, - Medianz Ho: Median, Median Median

Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) D-value State your conclusion O Reject Ho. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. Reject Ho. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference in the time required by the three methods. O Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference in the time required by the three methods.

You may need to use the appropriate appendix table or technology to answer this question. The gap between the earnings of men and women with equal education is narrowing but has not closed. Sample data for seven men and seven women with bachelor's degrees are as follows. Data are shown in thousands of dollars. Men Women 36.6 41.5 88.5 48.4 58.2 35.9 60.2 46.5 44.2 38.8 59.9 55.5 68.3 21.8 (a) What is the median salary (in $) for men? For women? men $ women

(b) Use a = 0.05 and conduct the hypothesis test for identical population distributions. State the null and alternative hypotheses. O Ho: Median salary for men - Median salary for women so Me: Median salary for men - Median salary for women > 0 Ho: The two populations of salaries are identical. Me: The two populations of salaries are not identical. O Ho: Median salary for men - Median salary for women 2 0 Mo: Median salary for men - Median salary for women < 0 O Ho: Median salary for men - Median salary for women > 0 He: Median salary for men - Median salary for women = 0 OH: The two populations of salaries are not identical. Me: The two populations of salaries are identical. Find the value of the test statistic. W- Find the p-value. (Round your answer to four decimal places.) p-value What is your conclusion? Reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women. Do not reject Ho. There is not sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women. Do not reject Ho. There is sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women. O Reject Ho. There is sufficient evidence to conclude that there is a significant difference between the annual salaries of men and women.
