# Test 2 Description

**Basic 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.

**Test 2 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**:

Paper |
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: ** 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.

**Problem Descriptions**:

1 - Find the mean and standard deviation of a quantitative frequency table as in #5(a) p.146. | Examples | |

1 - Use standard scores to compare items from different data sets as in #5-12 p.154. | Examples | |

1 - Identify the parameter and statistic in a study summary such as those given in #17-21 and #27 p.447 and #13-15 and #17-19 pp.457-58. | Examples | |

1 - Find basic table probabilities as in #21(a,b,d) and #24(a) p.288. | Examples | |

1 - Find not-so-basic table probabilities as in #21(c,e,f,g,h) and #22(b) p.288. | Examples | |

1 - Decide whether or not a discrete probability distribution exists as in #9-14 p.305. Note: "Yes" and "No" are NOT acceptable answers to these problems. |
Examples | |

1 - Compute the mean and standard deviation of a discrete probability distribution as in #18(c,d) and #19(c),(d) pp.305-06. | Examples | |

1 - Decide whether or not a binomial experiment exists as in #7-10 and #12-15 p.320. Note: "Yes" and "No" are NOT acceptable answers to these problems. |
Examples | |

1 - Compute binomial probabilities as in #35 (b,c,d), #36 (a,b,c), #37(b,c), #38(a,b), #39(a,b) and #40(a,b) p.321. | Examples | |

1 - Compute the mean and standard deviation of a binomial experiment as in #43 (a,b) and #44(a,b) p.322. | Examples |

Indicates the calculator has a routine which quickly does most of the work for the problem. |
