Question 1

A survey asked 200 students their favorite sport. 80 chose soccer. What is the relative frequency for soccer?

Accepted Answer

0.40

Answer

80 ÷ 200 = 0.40, so the relative frequency for soccer is 0.40 (or 40%).

Question 2

A histogram has bars of heights 3, 7, 12, 8, and 5 for intervals 0–10, 10–20, 20–30, 30–40, and 40–50. In which interval do most data values fall?

Accepted Answer

20–30

Answer

The tallest bar (height 12) corresponds to the 20–30 interval, meaning the most data values fall there.

In a perfectly symmetric bell-shaped (normal) distribution, the mean, median, and mode are all equal.
