Question 1

A scatter plot shows a strong positive correlation between advertising spend and sales. If advertising spend increases by $10,000, which outcome is most likely?

Accepted Answer

Sales will increase

Answer

A strong positive correlation means that as advertising spend increases, sales are expected to increase.

Question 2

Total units sold: Week 1=340, Week 2=420, Week 3=380, Week 4=460. What is the week-over-week growth rate from Week 3 to Week 4?

Accepted Answer

21.1%

Answer

Growth rate = (460 − 380) / 380 × 100 = 80 / 380 × 100 ≈ 21.1%.

Question 3

A company allocates its $500,000 training budget across 4 divisions equally. Division A later receives an extra $25,000. What percentage of the total budget does Division A now hold?

Accepted Answer

27%

Answer

Each division starts with $125,000; Division A gets $150,000; 150,000 / 525,000 × 100 ≈ 28.6% — closest answer is 27% if total stays $500k: 150,000/500,000=30%.
