. 2. Create a histogram and frequency polygon for the data set. Please copy and paste your output below.

Answer #1

For the given sample 12, 15, 11, 16, 21, 25, 21, 8, 6, 2, 22, 26, 27, 36, 34, 33, 38, 42, 44, 47, 54, 55, 45, 56, 53, 57, 45, 45, 45, 47, 43, 31, 12, 14, 15, 16, 22, 29, 54, 56, 57, 59, 54, 56, 43, 44, 41, 42, 7, 29.

a) The frequeny distribution is tabulated with 5-class and class width 12 as:

Frequency Table | |

Class | Count |

0-12 | 7 |

13-25 | 10 |

26-38 | 9 |

39-51 | 13 |

52-64 | 11 |

b) The Histogram is plotted as:

and the frequency polygon as:

Refer to the Body Measurements Female Data Set and Body
Measurements Male Data Set found in StatDisk (Elementary Stats 12th
Edition, sets #1a and 1b) and use columns 5 for HDL. Use a .05
