Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by 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:; .SST= 10,780; SSTR= 4,520
a. Set up the ANOVA table for this problem (to 2 decimals, if necessary).
| Source of Variation | Sum of Squares | Degrees of Freedom | Mean Square | F | p-value (to 4 decimals) |
| Treatments | |||||
| Error | |||||
| Total |
b.Use 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 -value is - Select your answer
-less than .01between .01 and .025between .025 and .05between .05 and .10greater than .10Item 12
What is your conclusion?
- Select your answer
-Conclude not all means of the three assembly methods are equalCannot reject the assumption that the means of all three assembly methods are equalItem 13

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: SST=10,740; SSTR=4,540

Three different methods for assembling a product were proposed
by an industrial engineer. To investigate the number of units
assembled correctly with each method, 27 employees were randomly
selected and randomly assigned to the three proposed methods in
such a way that each method was used by 9 workers. The number of
units assembled correctly was recorded, and the ANOVA was performed
on the resulting data set. The following results were obtained: SST
