Please answer all questions. THANKS!!

Q4} Suppose Sally was interested in determining whether there is a signicant difference in prices at three grocery stores (Provigo, Metro, and Adonis). Sally selected ve foods and recorded the price for each item in each store. Aer calculating the appropriate values, the following information was calculated: Store SS: 0.9053, MS: 0.4521r Food item SS: 1823.348, MS: 455.8371 Total SS: 1828.058 4a. Based on the test statistic {alpha of 0.05} for the price of foods, what does this tell you about the appropriateness of the experimental design (ie: blocking)? Explain your reasoning. Be sure to provide the critical value and calculated value. (I recommend completing an ANOVA table to help you complete this question). (2 points) 4b. Is there a signicant difference in the prices charged by the three stores at the 0.05 level of signicance? (1 point) 4c. Based on your answer to (4b), would it be helpful to test for the difference in treatment means using the Tukey method? If not, why? If so, complete the calculation (with alpha 0.05} and draw your conclusions. (2 points)
