Question

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: SST -10,890: SSTR 4,590. 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 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).

Answer 1

a)

Source	SS	df	MS	F	p vlaue
regression	4590	2	2295.00	9.84	0.0006
error	6300	27	233.33
total	10890	29

b)

vale of test statisitc F=9.84

p value <0.01 (or =0.0006)

we can conclude that not all treatment means are equal
