Effects of the price partitions

Reference no: EM131009355

1. What happens to the profile plot in Figure 1 if we reverse the rows and columns of the data? (Let Price Partition define the x-axis and connect points in the same region.) Sketch the new plot. Do you still see the presence of interaction?

2. We don't actually need further calculations to compare the effects of the price partitions within regions; everything we need is in Table 1 and Table 2. Using those tables, identify a statis- tically significant difference among the means in the Northeast. Be sure to adjust for multiple comparisons.
