Quizplus · Accepted Answer

The relative frequency for Juniors is 0.22, which means 22% of the total students are Juniors. The total frequency is 600 + 560 + 400 = 1560. To find the frequency for Juniors, calculate 0.22 * 1560 = 343.2. Since the frequency must be a whole number, the total frequency should be adjusted to 2000 (since 0.22 * 2000 = 440), making the missing number 440.
