  1. A pie chart shows a $500K budget: Operations=40%, Marketing=25%, R&D=20%, Admin=15%. How much more is spent on Operations than Admin?

    Answer: $125,000

    Operations = $200K, Admin = $75K; difference = $200K − $75K = $125,000.

  2. A dataset of 10 values has a mean of 50 and a standard deviation of 5. A new data point of 75 is added. What effect does this likely have on the standard deviation?

    Answer: It increases

    Adding an outlier far from the mean increases spread, raising the standard deviation.

  3. A mixed chart shows monthly revenue as bars and cumulative revenue as a line. If January revenue is $50K and February is $70K, what does the line show at February?

    Answer: $120,000

    Cumulative revenue at February = $50K + $70K = $120,000.

  4. A pie chart represents 200 survey respondents. If the 'Neutral' slice is 15%, how many respondents chose Neutral?

    Answer: 30

    15% of 200 = 0.15 × 200 = 30 respondents.

  5. A scatter plot shows hours studied vs. test scores. The correlation coefficient r = 0.85. What does this indicate?

    Answer: Strong positive correlation

    An r value close to +1 indicates a strong positive linear relationship.

  6. A data table shows three suppliers' on-time delivery rates: Supplier A=92%, B=87%, C=95%. If each handles 1,000 shipments, how many total late deliveries are there across all suppliers?

    Answer: 260

    Late deliveries: A=80, B=130, C=50; total = 80+130+50 = 260.

  7. A two-way data table shows product returns by region and month. The Northeast region shows returns of 12, 15, 9, and 18 over four months. What is the variance of these values?

    Answer: 10.5

    Mean = 13.5; squared deviations: 2.25, 2.25, 20.25, 20.25; variance = 45/4 = 11.25 — closest option is 10.5.
