Test 2 Information

General Information: Test 2 has 10 problems worth 6 points each for a total of 60 possible points. Test 2 is open book and closed notes.

​

Administration: Test forms will be handed out at the beginning of the period on the day the test is scheduled in class. You will have the whole period to write your answers on paper. When you have finished, you will turn in your answers and your test form to Dr. Gurney.

​

Materials Needed: Ruled notebook or graph paper (at least 2 sheets), Pencil (pens are allowed), Calculator (TI-83, TI-84 or comparable graphing calculator).

​

Accuracy of Answers

Computing probabilities: Use at least two, but no more than 4 decimal places.  If the probability can be written exactly with one decimal place, then you can leave it with one decimal place.

Computing basic statistics: Use at least one, but no more than two decimal place than is in the original data.  If the answer is exact with the same number of decimal places as the original data, then leave it like that.  If you use three or more decimal places than is in the original data, you will lose points for being too accurate.
