Select the correct answerThe arithmetic mean of the following numbers 1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6 and 7, 7, 7, 7, 7, 7, 7 is?Options414205
Solution
To find the arithmetic mean (also known as the average), you need to add up all the numbers and then divide by the quantity of numbers.
Here are the steps:
- Add up all the numbers: 1+2+2+3+3+3+4+4+4+4+5+5+5+5+5+6+6+6+6+6+6+7+7+7+7+7+7+7 = 119
- Count the quantity of numbers: There are 27 numbers.
- Divide the sum by the quantity: 119 ÷ 27 = 4.407407407407407
So, the arithmetic mean of the given numbers is approximately 4.41.
Therefore, the closest answer among the options is 4.
