Question

A financial advisor wants to market three plans as being equal in dividends paid per share. He collects sample data from each plan to compare the average dividends paid per share. Use the summary information in the table below, given the number in each sample, the sample average, and the sample variance, s^2.

Plan 1	Plan 2	Plan 3
1.28	1.05	0.45
1.55	1.14	1.15
1.91	1.15	0.20
1.95	3.07	1.00
0.75	1.56	0.30
2.68	0.60	0.66
2.03	1.31	1.09

Groups	Count	Average	Variance
Plan 1	7	1.735714	0.378062
Plan 2	7	1.411429	0.619048
Plan 3	7	0.692857	0.153057

(b)

Do the data provide convincing evidence to conclude that there is a significant difference among the average dividends paid per share for the three different plans at a 5% significance level? (Use a table or technology.)

Yes, there is convincing evidence that the average dividends paid per share for the three different plans is the same for all plans.Yes, there is convincing evidence that the average dividends paid per share for the three different plans are not all the same. No, there is not convincing evidence that the average dividends paid per share for the three different plans is not the same for at least one plan.No, there is not convincing evidence that the average dividends paid per share for the three different plans is not the same for all plans.
