# 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 Response Time, 2010 Frequency ( f ) 21 minutes or more 45 16-20 minutes 95 11-15 minutes 155 6-10 minutes 350 Less than 6 minutes 250 Total 895

Expert Solution
To determine

To Convert:

Frequency distribution into percentages.

### Explanation of Solution

The formula of percentage is:

Percentage: % = (fN)*100

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
