Valencia Orange Price Comparison
You have been hired as a consultant to determine who ABC Grocery Store should be ordering Valencia Oranges from.
To: Statistician
From: ABC Grocery Store
Please advise us on which company to use as our orange distributor. Three highly recommended distributors have provided us with statistical data on the weekly prices for one load of Valencia oranges per week for a ten-week period last year. Prices fluctuate according to availability, and we would like to use the company with the lowest overall price and the least amount of fluctuation. We would like your written report showing your results and a detailed recommendation as to which company we should choose.
Thank you.
