Question

The following data are the distances between 20 retail stores and a large distribution center. The distances are in miles.

29; 38; 39; 40; 58; 67; 68; 69; 76; 85; 86; 95; 96; 96; 99; 106; 112; 127; 145; 150

Use a graphing calculator or computer to find the standard deviation and round to the nearest tenth.

Answer #1

Sr. no | X | (X - X̄)² |

1 | 29 | 3030.50 |

2 | 38 | 2120.60 |

3 | 39 | 2029.50 |

4 | 40 | 1940.40 |

5 | 58 | 678.60 |

6 | 67 | 290.70 |

7 | 68 | 257.603 |

8 | 69 | 226.503 |

9 | 76 | 64.803 |

10 | 85 | 0.903 |

11 | 86 | 3.803 |

12 | 95 | 119.903 |

13 | 96 | 142.803 |

14 | 96 | 142.803 |

15 | 99 | 223.503 |

16 | 106 | 481.803 |

17 | 112 | 781.203 |

18 | 127 | 1844.703 |

19 | 145 | 3714.903 |

20 | 150 | 4349.403 |

X | (X - X̄)² | |

total sum | 1681 | 22444.95 |

n | 20 | 20 |

mean = ΣX/n = 1681.000
/ 20 = 84.0500

**sample std dev = √ [ Σ(X - X̄)²/(n-1)]
= √ (22444.95/19) =
34.4**

Using the accompanying Student Grades data, construct a scatter
chart for midterm versus final exam grades and add a linear
trendline. What is the model? If a student scores 7878 on the
midterm, what would you predict her grade on the final exam to
be?
