To investigate the nu 4. s crrectly with each method, 30 employees were randomly selected and randomly assigned to the three proposed methods in such a way assembled correctly was recorded, and the analysis of variance procedure was each method was used by 10 workers. The number of units 6. applied to the resulting data set. The following results were obtained: SST -10,860; SSTR 4,580. a. Set up the ANOVA table for this problem (to 2 decimals, if necessary). Source of Variation Sum of Squares Degrees of Freedom Mean SquareF p-value (to 4 decimals) Treatments Error Total b.Use a .05 to test for any significant difference in the means for the three assembly methods. Calculate the value of the test statistic (to 2 decimals). The p-value is between .05 and .10 What is your conclusion? Conclude not all means of the three assembly methods are equalExplanation / Answer
