Question

Complete the ANOVA table by filling blank spaces. (Answers written anywhere else, outside of the table, would not be considered) An investigator is interested in the effects of stress on the lime of assembling a part of an engine in a manufacturing company. She records assembly time of 21 workers with three groups of stress: one group (7 workers) that is under a great deal of stress, one group (7 workers) under a moderate amount of stress and a third group (7 workers) that is under almost no stress. Theory A suggests that subjects under different amount of stress have different performances (assembly time). Use given information and fill 7 blank spaces in the following ANOVA table.

Explanation / Answer

SSTR=MSTR*k-1

=42.35*2=84.7

F=MSTR/MSE

=42.35/4.85=8.732

SSE=MSE*n-k

=4.85*18=87.3

DF SS MS F Treatments k-1=3-1=2

SSTR=MSTR*k-1

=42.35*2=84.7

42.35

F=MSTR/MSE

=42.35/4.85=8.732

Error n-k=21-3=18

SSE=MSE*n-k

=4.85*18=87.3

4.85 Total n-1=20 SST=84.7+87.3=172
