Need some help with ANOVA & Chi please!!

You may need to use the appropriate technology to answer this question. In a completely randomized design, seven experimental units were used for each of the ve levels of the factor. Complete the following ANOVA table. (Round your values for MSE and Fto two decimal places, and your pvalue to four decimal places.) Treatments 3|]0 I I I I I I I Error | | | | | Total 440 |:| 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. Set up the ANOVA table for these data.
