Perform a formal ypothesis test freedom, the p-value, and your conclusion in context of the problem. to determine this: be sure to include your hypotheses, the test statistic, the degrees of Ha: At least one 0 F= 376 (directly from the table) p-value = 0.0256 (directly from the table) Since p-ralue c005, we can reject the null hypothesis. There is evidence vary across the 3 shelf locations in the population of all stores. here is evidence that sales truly

Explanation / Answer

Answer to the question below:

Yes. We have performed the ANOVA to get a F value of 3.759 with a significance of .026. This means that the p-value is less than .05, meaning the F-test is significance. We must reject the null hypothesis in this case. The beta coefficients are statistically different from each other and thereofre, middle and top sales are statistically different.
