# Test 1 Description

**Basic Information**: Test 1 has 10 problems worth 6 points each for a total of 60 possible points. Test 1 is closed book and closed notes.

**Test Administration**: Test forms will be handed out in class on the day scheduled for the test, and you will have the whole class period to answer each of the ten problems on your own paper. When you are finished, you will turn in your answers and your test form to Dr. Gurney.

**Materials Needed**:

Paper |
ruled notebook paper |

at least 2 sheets | |

Pencil |
pens are allowed |

Calculator |
TI83, TI84 or comparable graphing calculator |

**Accuracy of Answers: ** When finding basic statistics, you should use at least one more decimal place than is in the original data unless the answer comes out exactly to something with less decimal places. I will allow two more decimal places than is used in the original data, but if you use three or more decimal places than is in the orginal data, you will lose points for being too accurate.
