READ instruction sheet
| There are three sheets in the EXCEL file. |
| Complete the problems in each excel sheet, all calculations must be done within the excel file and show your calculation in order to receive credit. |
| Must enter your final answers in the designated BOX to receive FULL credit. |
| This is an individual project so each student must submit: |
| a hard copy of of completed excel work (including graphs) in class by 10/5/2017; |
| AND an e-copy of the completed excel file via blackboard by 10/5/2017 at 2:00pm. Checking your e-copy is for potential partial credits. |
