• Assignment Instructions
• A retail store has recently hired you as a
  consultant to advise on economic conditions. One
  important indicator that the retail store is
  concerned about is the unemployment rate. The
  retail store has found that an increase in the
  unemployment rate will cause a lack of consumer
  spending in their stores. Retail stores use the
  unemployment rate to estimate how much inventory
  to keep at their stores, which is important in
  maintaining cost effectiveness. In this
  consultant role you will apply calculations and
  research to create a predictive sales report.
