Must complete all the parts to this problem:
- PART 1: Perform a simple linear regression in Excel to predict Annual Food Spending by Annual Household Income and output the results. Include the Regression Statistics, ANOVA, and table of Coefficients for each model.
- PART 2: Suppose a households annual income is $60,000. Predict how much they spend on food per year. Write the model and show the work to get the answer.
- PART 3: Now, develop a regression model to predict Annual Food Spending by Annual Household Income for those living in the Metro area only and output the results. Include the Regression Statistics, ANOVA, and table of Coefficients for each model.
- PART 4: Suppose a households annual income for those living in the metro area only is $60,000. Predict how much they spend on food per year. Write the model and show the work to get the answer.
