Not what you're looking for?
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:
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 models. How could CoffeeTime further optimize this model and explain?
Tourism is one consideration for CoffeeTime's future. A survey of 1,233 visitors to Mumbai last year revealed that 110 visited a small cafe during their visit. Laura claims that 10% of tourists will include a visit to a cafe. Use a 0.05 significance level to test her claim.
