4. On a new worksheet named "Simulation" (no quotes), use the high and low limits you just calculated to simulate daily requirements for each customer to obtain a combined daily requirement. In cell A3, enter "Day". Copy the customer numbers from the Bearing Data sheet and paste them in Simulation in cells B3-K3. In column A, starting in cell A4, create a numeric list of days (A4 will be 1, A5 will be 2, etc.) up to 240. Assume that the daily requirements will vary for each customer randomly between the high and low limits you have calculated from the existing 30-day data for that customer. Generate the data for 240 instances (days) for each customer in cells B4:K243
