Question:
If you are the manager of a grocery company with 50 stores across the city. The excel file contains data on the demand for grocery delivery:
Delivery (Y) is the number of delivery per month
Price (X1) is the average price of a delivery
Income (X2) is average income in the neighbourhood

You are required to use the Microsoft Excel package (the data analysis section) to finish the specific tasks below.
Task 1: Trend Line (Curve-Fitting) AnalysisPlot the scatter plot for #Delivery (y-axis) and Income (x-axis). Add the trendline with the equation and R-square. Interpret the R-square and comment on the slope coefficient. Suggest one use or application for this information.
Task 2: Simple RegressionEstimate the regression model for #delivery (Y) against price (X1). Interpret the estimated value of the coefficient for price. What are the values of the 95% confidence interval for price and what does it mean? Plot and comment on the residuals
Task 3: Multiple RegressionEstimate the regression model for #delivery (Y) against price (X1) and income (x2). What does the Rsquare say about the model? Why is the R-square in this model higher than the model in task 2 (both in terms of statistical and economics principles? Comment on the coefficients of price and income. Why is the coefficient of price different in this model than the one in task 2 (both in terms of statistical and economics principles? What is the substitution rate/ratio or trade-off between income and price, keeping quantity demanded constant?
Task 4: Application• If you were to buy a franchise and two locations were offered to you, with the following characteristics:
Location Alpha | Location Beta | |
Average Price | 18 | 23 |
Average Income | 60,000 | 45,000 |
If the cost of delivery is $5 a parcel and overheads (fixed cost) are the same for both locations ($3000), which option would you choose. Provide evidence to support your choice.
