Can you help with this practice question?

F = 35.6364, p-value = 0.0003; HO: there is a In sales methods (b) Test the null hypothesis #o that no differences exist between the effects of the salesmen (blocks) on mean weekly sales. Set a = .05. Can we conclude that the different salesmen have different effects on mean weekly sales? F = 12.6364, p-value = 0.0071; HO: salesman have an effect on sales. (c) Use Tukey simultaneous 95 percent confidence intervals to make pairwise comparisons of the sales method effects on mean weekly sales. Which sales method(s) maximize mean weekly sales? (Round your answers to 3 decimal places. Negative amounts should be indicated by a minus sign.) Method 1 - Method 2: Method 1 - Method 3: Method 1 - Method 4: Method 2 - Method 3: Method 2 - Method 4: Method 3 - Method 4:A marketing organization wishes to study the effects of four sales methods on weekty sales of a product. The organization employs a randomized block design In which three salesman use each sales method. The results obtained are given In the following table. along with the JMP output of a randomized block AN OVA of these data. 32 29 36 32 36 26 26 24 23 25 24 23 #WNl-l nodal 5 121.16663 24.2333 26.6364 Error 6 5.56666 6.9163 Prob 2 F C.
