Chapter 13.3, Problem 14E

The following data are from a completely randomized design. In the following calculations, use α = .05.

	Treatment	Treatment	Treatment
	1	2	3
	63	82	69
	47	72	54
	54	88	61
	40	66	48
${\bar{x}}_j$	51	77	58
$s_j^2$	96.67	97.34	81.99

1. a. Use analysis of variance to test for a significant difference among the means of the three treatments.
2. b. Use Fisher’s LSD procedure to determine which means are different.
