Use the 5-step solution for each of the following problems.

Example:

1. Ho: = = =

;

Ha: Not all the are equal or at least one pair of means is significantly different.

2. = 0.01, = 0.105792

3. Decision Rule: Reject Ho if p-value

4. Decision: Do not reject Ho

5. Conclusion: There is no significant difference in the average number of bottles of vinegar sold.

1. To examine the effects of work environment on attitude towards work, an industrial psychologist randomly assigned a group of newly-hired production workers to three different rooms. Six trainees were randomly assigned in three rooms, which were identical except for the color of the walls. The first room was blue, the second was green, and the third was yellow. During the training period, the trainees stayed mostly in their rooms. At the end of the training, an attitude scale towards work was administered. The following data were gathered. Use=0.05.

Blue	Green	Yellow
50	59	43
45	49	51
54	54	48
42	38	55
58	40	47
36	36	57

1. Perform post-ANOVA test if the decision arrived at is to reject Ho.
2. If you are the industrial psychologist, what work station will you recommend to the production manager? Why?
