A supermarket wants to test the effect of the height of the shelf display on the monthly sales of its dairy products, Y. There are three-
shelf heights: bottom, X1, middle, X2, and top, X3. The estimated model is given by:
= 28.3 4.7 X1 + 3.5 X2 - 2.1 X3
The p-value for the F-test on the joint significance of shelf height is equal to 0.161, and you...
A reject the null hypothesis, height helps explaining dairy sales
B
cannot reject HO, height does not help explaining dairy sales
cannot reject H0, height helps explaining dairy sales
(D) reject the null hypothesis, height does not help explaining dairy sales
