Question
The percentages of police officers who are women are listed in the table for various city populations. City Population (in thousands) Value Used to Represent City Population (in thousands) Percent 0-9.999 8.3 10-24.999 17.5 7.5 25-49.999 37.5 8.5 50-99.999 75 9.4 100-249.999 175 11.7 250 or more 300 17 Source: FBI Uniform Crime Report Let f(n) be the percentage of police officers who are women in cities with populations of n thousand. A quadratic model of the situation is f(n) = 0.00006n² + 0.012n + 7.884. Use a graphing calculator to draw the graph of the model and, in the same viewing window, the scattergram of the data. Does the model fit the data well? O The function is a good model for the data. O The function is not a good model for the data Glen Ellyn, Illinois, has a population of 164.83 thousand. Estimate the percentage of police officers in Glen Ellyn who are women. Round to 1 decimal place. Find the values of n when f(n) = 8. Be sure to find both values of n separated by a comma. n = Round each to 1 decimal place. What does it mean in this situation? (Answer this question on scratch paper prior to looking at the choices.)
