  1. Reference Table: Monthly Incident Reports Type | Jan | Feb | Mar Theft | 45 | 38 | 52 Assault | 22 | 25 | 20 Vandalism | 30 | 35 | 28 Traffic | 60 | 55 | 65 According to the table, what was the total number of incidents reported in January?

    Answer: 157

    To find the total for January, you must sum all the values in the 'Jan' column. The calculation is 45 (Theft) + 22 (Assault) + 30 (Vandalism) + 60 (Traffic), which equals 157.

  2. Using the same incident report table, how many more theft incidents were reported in March than in February?

    Answer: 14

    First, find the number of theft incidents for March (52) and February (38). Then, subtract the February value from the March value to find the difference: 52 - 38 = 14.

  3. Based on the incident report table, which incident type had the highest number of reports in March?

    Answer: Traffic

    To answer this, look at the 'Mar' column and compare the values for each incident type. The values are Theft (52), Assault (20), Vandalism (28), and Traffic (65). The highest value is 65, which corresponds to Traffic incidents.

  4. Reference Chart: A bar chart shows arrests by shift for the first quarter: Day Shift - 120 arrests, Evening Shift - 150 arrests, Night Shift - 90 arrests. What was the total number of arrests made across all three shifts?

    Answer: 360

    To find the total number of arrests, you must add the number of arrests from each shift together. The calculation is 120 (Day) + 150 (Evening) + 90 (Night), which equals 360.

  5. Using the same arrest chart data (Day: 120, Evening: 150, Night: 90), how many more arrests were made by the Evening Shift compared to the Night Shift?

    Answer: 60

    This question requires comparing the values for the Evening Shift and the Night Shift. Subtract the number of Night Shift arrests from the number of Evening Shift arrests: 150 - 90 = 60.

  6. Using the incident report table, which month had the lowest number of reported Vandalism incidents?

    Answer: March

    Locate the 'Vandalism' row in the table. Compare the values for each month: January (30), February (35), and March (28). The lowest of these three values is 28, which occurred in March.
