Laura wanted to build a multiple regression model based on advertising
expenditures and coffee times price index. Based on the selection of all
normal values she obtained the following:
Multiple R = 0.738
R-square = 0.546
By using lagged values she came up with the following:
Multiple R = 0.755
R-square = 0.570
Explain the differences in using these different models. How could
CoffeeTime further optimize this model?
Tourism is one consideration for CoffeeTime’s future. A survey of
1,233 visitors to Mumbai last year revealed that 110 visited a small
cafй during their visit. Laura claims that 10% of tourists will include
a visit to a cafй. Use a 0.05 significance level to test her claim.
Would it be wise for her to use that claim in trying to convince
management to increase their advertising spending to travel agents?
Explain.
Finally, what additional strategy (or variation on a given strategy)
would you recommend to the key decision maker in the simulation to solve
the challenge given? Prepare a 350-word memo to the simulation's key
decision maker advocating your recommendation

This solution explains how to interpret the results of regression models and to judge which model is better. It discusses the current effect and stock effect of advertising expenditure while deciding on which model is better.
