Answer

Answer:

a. Horror sales appear to be only 50% of fantasy sales, but they are actually only about 8% smaller.

Explanation:

Step1: Visual - estimate percentage

Visually, horror bar seems half of fantasy bar, so appears 50% of fantasy sales.

Step2: Assume actual values

Let's assume fantasy sales = 52 and horror sales = 48 (from graph values).

Step3: Calculate actual percentage difference

The formula for percentage difference is $\frac{\text{Fantasy}-\text{Horror}}{\text{Fantasy}}\times100%$. Substituting values: $\frac{52 - 48}{52}\times100%=\frac{4}{52}\times100%\approx 7.69%\approx8%$.
