Your city has recently decided to reduce policing costs by switching from one officer cars to two
officer cars. The police chief has commissioned you to test whether policing costs have
decreased in response to the switch to two officer cars for all four districts. Test whether there is
a significant difference in the average police costs between one officer and two officer cars at the.05 level. Make sure you apply the nine steps of this hypothesis test!When calculating the standard deviation, you will need to: a. Have the difference scores #1 above; b. subtract out the mean of differences (-1468.75) from each of the difference scores; c. square those deviations; d. sum those deviations; e. divide by n-1; f. take the square root.
