In the distribution with X values 5, 4, 3, 2, 1 and corresponding frequencies 2, 8, 5, 3, 2, what percentage have X = 1?

In the distribution with X values 5, 4, 3, 2, 1 and corresponding frequencies 2, 8, 5, 3, 2, what percentage have X = 1?

• A. 5%
• B. 10%
• C. 15%
• D. 20%

Answer: (B)

In a frequency distribution, the percentage for a specific value is its frequency divided by the total frequency, times 100. First add all frequencies: 2 + 8 + 5 + 3 + 2 = 20. The frequency for X = 1 is 2. So the percentage is (2 / 20) × 100 = 10%. Therefore, 10% have X = 1. The other options would require different frequencies for X = 1 (for example, 1 would give 5%, 3 would give 15%, 4 would give 20%).
