(a) There are 3 treatments, therefore k = 3 and DF1 = 3 - 1 = 2
Total Observation = 30. DF2 = N - k = 30 - 3 = 27
Given SSTR = 4590
MSTR = SSTR / DF1 = 4590 / 2 = 2295
SS error = SST - SSTR = 10890 - 4590 = 6300
MS error = SS error / DF2 = 6300 / 27 = 233.33
Therefore F = MSTR / MS error = 2295 / 233.33 = 9.84
The Complete ANOVA table is below
Source | Sum of Squares | DF | Mean Square | F | p value |
SSTR | 4590 | 2 | 2295.00 | 9.84 | 0.0006 |
Error | 6300 | 27 | 233.33 | ||
Total | 10890 | 29 |
(b) The Test Statistic = F = 9.84
The p value is p < 0.001
Conclusion: There is sufficient evidence to conclude that there is a significant difference in the means for the three assembly methods.

Спеск My work oo eBook 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 by 10 workers. 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:...
