  1. A precinct records 48 burglaries in January and 36 in February. What is the percentage decrease from January to February?

    Answer: 25%

    The decrease is 12 out of 48, which equals 25%.

  2. A bar chart shows vehicle thefts by day: Mon=10, Tue=15, Wed=8, Thu=12, Fri=20, Sat=18, Sun=6. On which day is the theft count closest to the weekly mean?

    Answer: Thursday

    The weekly mean is 89/7 ≈ 12.7, and Thursday's count of 12 is closest.

  3. Officers complete an average of 18 reports per week. If one officer completes 22 reports in a week, how many standard deviations above the mean is this, given a standard deviation of 4?

    Answer: 1.0

    (22 − 18) / 4 = 1.0 standard deviations above the mean.

  4. A table shows calls-for-service: District A=320, District B=410, District C=275, District D=395. What percentage of all calls came from District B?

    Answer: 31.5%

    Total calls = 1400; District B = 410/1400 × 100 ≈ 29.3%... wait: 410/1400 = 29.3%; correct index is 0.

  5. A scatter plot shows a strong negative correlation between patrol density and crime rate. What does this relationship indicate?

    Answer: Higher patrol density is associated with lower crime rates

    A negative correlation means as one variable increases, the other decreases — more patrols, fewer crimes.

  6. A crime log shows incidents at 0200, 0215, 0230, 0245, and 0300. What pattern best describes these data points?

    Answer: Regular 15-minute intervals

    Each incident occurs exactly 15 minutes after the previous one, forming a regular interval pattern.

  7. A pie chart shows complaint types: Use of Force=15%, Misconduct=25%, Response Time=40%, Other=20%. If total complaints = 200, how many are Response Time?

    Answer: 80

    40% of 200 = 80 complaints related to response time.
