You may need to use the appropriate technology to answer this question A company manufactures printers and tax 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 employees was selected from each plant and the employeur selected were given a quality awareness examination. The examination scores for those 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 Atlanta Plant 2 Dallas Plant 3 Seattle 70 59 59 BBS 24 02 69 G Sample menn . 3 Sample variance Sample Standard deviation Set up the ANOVA table for these data. (Round your values for MSE and Fto two decimal places, and your p-value to four decimal places Source of Variation Sum of Squares Degrees of Freedom Mean 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. Ho Not all the population means are equal H = M H3 Ho: At least two of the population means are equal. H:At least two of the population means are different O Hot Hy H = 1 H2= Hot H = HH2 Hoi Hy = 424 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 Reject H, There is sufficient evidence to conclude that the means for the three plants are not equal. Do not reject Ho. There is sufficient evidence to conclude that the means for the three plants are not equal. Do not reject Ho. There is not 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 Need Help? Read it
