Question 1: The bar chart below shows the number of reported property crimes in the Fortitude Valley district for June. Which type of crime was reported most frequently? **Chart Data:** - Unlawful Entry: 45 - Vehicle Theft: 30 - Other Theft: 60 - Property Damage: 25
- Unlawful Entry
- Vehicle Theft
- Other Theft (Correct answer)
- Property Damage
Correct answer: Other Theft
By comparing the values for each category, 'Other Theft' has the highest number of reported incidents at 60. This is higher than Unlawful Entry (45), Vehicle Theft (30), and Property Damage (25).
Question 2: The table below shows the number of traffic infringements issued by a Road Policing Unit over four quarters. In which quarter was there the largest increase in infringements compared to the previous quarter? **Table Data:** - Quarter 1: 210 - Quarter 2: 250 - Quarter 3: 275 - Quarter 4: 335
- Quarter 1
- Quarter 2
- Quarter 3
- Quarter 4 (Correct answer)
Correct answer: Quarter 4
Calculate the increase between each quarter: Q2-Q1 = 40 (250-210); Q3-Q2 = 25 (275-250); Q4-Q3 = 60 (335-275). The largest increase of 60 occurred between Quarter 3 and Quarter 4, meaning the increase was in Quarter 4.
Question 3: The table shows police response times for Priority 2 calls on a single day. What was the average response time in minutes? **Table Data (in minutes):** - Call 1: 12 - Call 2: 15 - Call 3: 9 - Call 4: 10
- 10.5 minutes
- 11.5 minutes (Correct answer)
- 12 minutes
- 46 minutes
Correct answer: 11.5 minutes
To find the average, you sum the values and divide by the number of values. The sum is 12 + 15 + 9 + 10 = 46. The number of calls is 4. Therefore, the average is 46 / 4 = 11.5 minutes.
Question 4: A police station's annual budget is $2,000,000. A pie chart shows that 35% of the budget is allocated to Officer Salaries. How much money is allocated to Officer Salaries?
- $350,000
- $500,000
- $700,000 (Correct answer)
- $1,300,000
Correct answer: $700,000
To find 35% of $2,000,000, you can convert the percentage to a decimal (0.35) and multiply. $2,000,000 * 0.35 = $700,000. This is the amount allocated to salaries.
Question 5: The bar chart shows the number of noise complaints by day of the week. What is the total number of complaints for the weekend (Saturday and Sunday)? **Chart Data:** - Mon: 10 - Tue: 8 - Wed: 12 - Thu: 15 - Fri: 30 - Sat: 45 - Sun: 35
- 75
- 65
- 80 (Correct answer)
- 155
Correct answer: 80
To find the total for the weekend, you need to add the number of complaints for Saturday and Sunday. According to the data, this is 45 (Saturday) + 35 (Sunday) = 80.
Question 6: A police vehicle travels at an average speed of 60 km/h to an urgent call 5 km away. How long will it take to arrive?
- 3 minutes
- 5 minutes (Correct answer)
- 6 minutes
- 12 minutes
Correct answer: 5 minutes
Time = Distance / Speed. The distance is 5 km and the speed is 60 km/h. Time = 5/60 hours. To convert this to minutes, multiply by 60. (5/60) * 60 = 5 minutes.
Question 7: The table below shows crime clearance rates for two years. Which crime type saw the biggest percentage point improvement in its clearance rate from Year 1 to Year 2? **Table Data:** - Assault: Year 1 (65%), Year 2 (70%) - Burglary: Year 1 (15%), Year 2 (22%) - Vehicle Theft: Year 1 (20%), Year 2 (24%) - Fraud: Year 1 (30%), Year 2 (33%)
- Assault
- Burglary (Correct answer)
- Vehicle Theft
- Fraud
Correct answer: Burglary
Calculate the percentage point difference for each crime: Assault (70-65=5), Burglary (22-15=7), Vehicle Theft (24-20=4), Fraud (33-30=3). The largest improvement was 7 percentage points for Burglary.
