Statistics Davidson College Economics 105, Aug - Dec 2005 Mark C. Foley Review # 1 Directions: This review is untimed, closed-book, closed-notes (except for your formula sheet). You should use Exce/ to do your work (and thus rounding will not be necessary), but may also use a calculator. Report all final answers to 3 decimal places, unless otherwise directed, and don't round, just report the 3 decimal places you see in Excel. Remember to write out the formulas and fill in their parts by copying values from your Excel worksheet. There are 100 points on the exam. Each problem is worth 20 points. You must show all your work to receive full credit. Any assumptions you make and intermediate steps should be clearly indicated. Do not simply write down a final answer to the problems without an explanation. Note: the Excel function for raising e to a power, as in e”, is “exp(2)". So you'd type “=exp(2)" into a cell, and see 7.389056. Please turn in your formula sheet with your exam. Carpe diem. Honor Pledge Start times End times
