Question 1

A local consumer reporter wants to compare the average costs of grocery items purchased at three different supermarkets, A, B, and C. Prices (in dollars) were recorded for a sample of 60 randomly selected grocery items at each of the three supermarkets. In order to reduce item-to-item variation, the prices were recorded for each item on the same day at each supermarket.

The results of the Bonferroni analysis are summarized below.
___________________
________________
Supermarket A     B   C
Mean Price 1.66   1.80 1.94

Fully interpret the Bonferroni analysis.

Question 2

Suppose an experiment utilizing a random block design has 4 treatments and 10 blocks for a total of 40 observations.  Assume that the total Sum of Squares for the response is SS(Total) = 300. If the Sum of Squares for Treatments (SST) is 20% of SS(Total), and the Sum of Squares for Blocks (SSB) is 40% of SS (Total),  find the F values for this experiment.
◦ treatments: F = 3.38; blocks: F = 2.70
◦ treatments: F = 6.5; blocks: F = 4.33
◦ treatments: F = 4.50; blocks: F = 3.00
◦ treatments: F = 20.83; blocks: F = 6.94

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
