Question

The following Excel output represents an attempt to determine if the two sets of data (Variable 1 and Variable 2) have equal variances. Based on the information shown would you accept the hypothesis of equal variances? You must show how you came to your conclusion

	Variable 1	Variable 2
Mean	2.21	2.01
Variance	2.95	3.58
Observations	20	20
df	19	19
F	0.82
P(F<=f) one-tail	0.04
F Critical one-tail	0.46

Answer 1

Also P(F<=f) one-tail =0.04 <0.05 Significance level. We cannot reject the null hypothesis of equal variance.

Based on the information shown would you accept the hypothesis of equal variances?

Yes.
