What is the mean of the numbers 2, 3, 5, 7, and 11?

What is the mean of the numbers 2, 3, 5, 7, and 11?

• A. 4.8
• B. 5.6
• C. 6.0
• D. 7.0

Answer: (B)

To find the mean of a set of numbers, you add together all the numbers and then divide by the total count of the numbers. In this case, the numbers to consider are 2, 3, 5, 7, and 11. First, add the numbers together: 2 + 3 + 5 + 7 + 11 = 28. Next, count how many numbers there are. Here, there are five numbers. Now, divide the sum by the count: 28 ÷ 5 = 5.6. Thus, the mean of the numbers 2, 3, 5, 7, and 11 is 5.6, confirming that this answer is indeed correct. Understanding this process is crucial as it applies to any set of numbers when finding the mean, making it a fundamental concept in statistics.
