A company manufactures printers and fax machines at plants located in Atlanta, Dallas, and Seattle. To measure how much employees at these plants know about quality management, a random sample of 6 employees was selected from each plant and the employees selected were given a quality awareness examination. The examination scores for these 18 employees are shown in the following table. The sample means, sample variances, and sample standard deviations for each group are also provided. Managers want to use these data to test the hypothesis that the mean examination score is the same for all three plants Plant 1 |Plant 2 Plant 3 Atlanta Dallas Seattle 84 71 60 75 75 82 73 61 77 75 68 70 69 76 30 87 56 Sample 7B 75 66 mean Sample 26.0 40.0 variance 33.2 Sample standard 5.10 6.32 5.76 deviation Set up the ANOVA table for these data. (Round your values for MSE and F to two decimal places, and your p-value to four decimal places.) Source Sum Degrees Mean of Variation of Squares of Freedom Square p-value Treatments Error Total Test for any significant difference in the mean examination score for the three plants. Use a = 0.05. State the null and alternative hypotheses. O Ho: Not all the population means are equal. Ha: H1 = H2 = H3 O Ho: At least two of the population means are equal. Ha: At least two of the population means are different. O Ho: #1 # #2 * H3 Ha: M1 = H2 = H3 O Ho: M1 = #2 = Mg O Ho: M1 = H2 = H3 Ha: Not all the population means are equal. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. O Do not reject Ho. There is sufficient evidence to conclude that the means for the three plants are not equal. O Reject Ho. There is sufficient evidence to conclude that the means for the three plants are not equal. O Reject Ho. There is not sufficient evidence to conclude that the means for the three plants are not equal.DETAILS ASWSBE13 13.E.023.MI.

There is not sufficient evidence to conclude that the means of the four treatments are not all equal. O Reject Ho. There is not sufficient evidence to conclude that the means of the four treatments are not all equal. O Do not reject Ho. There is sufficient evidence to conclude that the means of the four treatments are not all equal. O Reject Ho. There is sufficient evidence to conclude that the means of the four treatments are not all equal.7. DETAILS ASWSBE13 13.E.031.MI. MY NOTES ASK YOUR TEACHER You may need to use the appropriate technology to answer this question. An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been roposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use a = 0.05. Type of Ride Roller Coaster Screaming Demon Log Flume 41 52 50 Method 1 43 44 46 49 50 48 Method 2 51 46 44 Find the value of the test statistic for method of loading and unloading. 1.2 Find the p-value for method of loading and unloading. (Round your answer to three decimal places.) p-value = 0.315 State your conclusion about method of loading and unloading. O Because the p-value > @ = 0.05, method of loading and unloading is not significant. Because the p-value s a = 0.05, method of loading and unloading is not significant. O Because the p-value > a = 0.05, method of loading and unloading is significant. O Because the p-value s a = 0.05, method of loading and unloading is significant. Find the value of the test statistic for type of ride. 0.4 Find the p-value for type of ride. (Round your answer to three decimal places.) p-value = 0.687 State your conclusion about type of ride. Because the p-value > @ = 0.05, interaction between method of loading and unloading and type of ride is not significant. Because the p-value s a = 0.05, interaction between method of loading and unloading and type of ride is not significant. O Because the p-value > a = 0.05, interaction between method of loading and unloading and type of ride is significant
