  1. A trend line in a scatter plot has a negative slope. As variable X increases, variable Y most likely:

    Answer: Decreases

    A negative slope means as X increases, Y tends to decrease.

  2. A table shows sales rep performance: Rep A closed 18 deals with avg value $5K, Rep B closed 30 deals with avg value $2K. Who generated more total revenue?

    Answer: Rep A with $90K

    Rep A: 18×$5K=$90K; Rep B: 30×$2K=$60K, so Rep A generated more.

  3. A line chart shows inventory levels: Week 1=500, Week 2=420, Week 3=340, Week 4=260. If the trend continues, what is the expected Week 5 inventory?

    Answer: 180

    Inventory decreases by 80 each week (500→420→340→260), so Week 5 = 260−80 = 180.

  4. A frequency table shows test scores: 50-59=5 students, 60-69=12, 70-79=20, 80-89=10, 90-99=3. What percentage of students scored 70 or above?

    Answer: 66%

    Students scoring 70+ = 20+10+3 = 33 out of 50 total = 66%.

  5. Two pie charts show customer satisfaction for 2022 and 2023. 'Very Satisfied' went from 35% to 42% while the total customer base grew from 10,000 to 12,000. How many more 'Very Satisfied' customers were there in 2023 vs 2022?

    Answer: 1,540

    2022: 35%×10,000=3,500; 2023: 42%×12,000=5,040; difference=1,540.

  6. A bar chart shows that a region's GDP grew from $800B to $920B. Which of the following correctly expresses this as a ratio of new to old?

    Answer: 1.15:1

    920/800 = 1.15, so the ratio of new to old GDP is 1.15:1.

  7. A chart shows that Product X has a 15% return rate. If 3,400 units were sold, approximately how many units were NOT returned?

    Answer: 2,890

    Units returned = 15% × 3,400 = 510; units not returned = 3,400 − 510 = 2,890.
