| Ohio 40 42 42 37 45 North Dakota 44 44 46 44 42 41 Montana 46 44 41 44 39 42 Indiana 42 39 40 43 41 The table gives the ages of randomly chosen people from 4 different states At a = 0.01, determine whether there is a difference in mean ages. 1. The null hypothesis is Ho: OH = H2 = 3 OH = H2 = H3 = H4 = 45 Oui = ly = H3 = HA 2. This is a right tailed test with: d.f.n - and d.f.de 3a. The STS (to 2 decimals) is F = 3b. The P-value (to 3 decimals) is: 4a. At a = 0.01, the decision is: Accept Ho О Accept Ha O Reject Ho Do not reject Ho 4b. The conclusion is: There is sufficient evidence to conclude that the mean ages in the states are the same There is insufficient evidence to conclude that the mean ages in at least two of the states are different There is sufficient evidence to conclude that the mean ages in at least two of the states are different There is insufficient evidence to conclude that the mean ages in the states are the same
