Question

(f) Suppose you and your business associates rent a store, get a bank loan to start up your business, and do a little research on the size of your sales district and the number of competing stores in the district. If x₂ = 2.8, x₃ = 250, x₄ = 3.1, x₅ = 7.3, and x₆ = 2, use a computer to forecast x₁ = annual net sales and find an 80% confidence interval for your forecast (if your software produces prediction intervals). (Use 2 decimal places.)

(g) Construct a new regression model with x₄ as the response variable and x₁, x₂, x₃, x₅, and x₆ as explanatory variables. (Use 2 decimal places for the intercept, 4 for x₁, 5 for x₃, and 3 otherwise.)

Suppose an All Greens store in Sonoma, California, wants to estimate a range of advertising costs appropriate to its store. If it spends too little on advertising, it will not reach enough customers. However, it does not want to overspend on advertising for this type and size of store. At this store, x₁ = 163, x₂ = 2.4, x₃ = 188, x₅ = 6.6, and x₆ = 10. Use these data to predict x₄ (advertising costs) and find an 80% confidence interval for your prediction. (Use 2 decimal places.)

At the 80% confidence level, what range of advertising costs do you think is appropriate for this store? (Round to nearest integer.)
