** PA/CJ** As part of an evaluation of the efficiency of your local police force, you have gathered the following data on police response tie to calls for assistance during two different years. (Response times were rounded off to whole minutes.) Convert both frequency distributions into percentages, and write a paragraph comparing the changes in response time between the two years.

Response Time, 2000 |
Frequency (f) |

21 minutes or more | 20 |

16-20 minutes | 90 |

11-15 minutes | 185 |

6-10 minutes | 370 |

Less than 6 minutes | 210 |

Total | 875 |

Expert Solution

To determine

**To Convert:**

Frequency distribution into percentages.

The formula of percentage is:

Percentage: % =

Where,

*f* = frequency, or the number of cases in a specific category

*N* = the number of cases in all categories

For the year 2000,

Response Time, 2000 |
Frequency (f) |
Percentages (%) |

21 minutes or more | 20 | 2.29 |

16-20 minutes | 90 | 10.29 |

11-15 minutes | 185 | 21.14 |

6-10 minutes | 370 | 42.29 |

Less than 6 minutes | 210 | 24 |
