    Sally wanted to build a multiple regression model based on advertising expenditures and A coffee business price index. Based on the selection of all normal values she obtained the following:
    1. Multiple R = 0.738 2. R square=0.546
    By using lagged values she came up with the following:
    3.Multiple R=0.755 4. R square=0.570
    Explain the differences in using these different methods. How could the Coffee business further optimize this model.
    Tourism is one consideration for The coffee future. A survey of 1,233 visitors to India last year revealed that 110 visited a small cafe during their visit.

Would it be wise for her to use that claim in trying to convince management to increase their advertising spending to travel agents? Explain.
