Calculate the between-treatments

Reference no: EM1318558

To find out the estimate of between and within treatments.

Samples were selected from 3 populations. The data obtained follow.

Sample 1	sample 2	sample 3
93	77	88
98	87	75
107	84	73
102	95	84
85	75	82

X_j	100	85	79
S_j2	35.33	35.6	43.5

a. calculate the between-treatments estimate of the standard deviation (to the second power).
b. calculate the within- treatment estimate of the standard deviation to the second power.
c. At the α = .05 level of significance, can we reject the null hypothesis that the three population means are equal? Explain.
d. Set up the anova table for this problem.
