Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method,30 employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by10workers. The number of units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting data set. The following results were obtained:

WITH A SST OF = 10,780 AND SSTR OF = 4,560.

Set up a anova table rounding all values to 2 decimal places and p value to four decimal places.

Use a .05 confidence level to test for any significant difference in the means for the three assembly methods.

Calculate the value of the test statistic (to 2 decimals).

REPEAT THIS WITH A SST OF : 10,810 AND A SSTR OF = 4,510
