The 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?

To calculate the arithmetic mean (also known as the average) of a set of numbers, you need to add all the numbers together and then divide by the count of the numbers.

Here are the steps:

1. Add all the numbers together: 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

2. Count the total number of numbers: There are 27 numbers in total.

3. Divide the sum of the numbers by the count of the numbers: 119 ÷ 27 = 4.407407407407407

So, the arithmetic mean of the given numbers is approximately 4.41 (rounded to two decimal places).
