Question

find the mean of:
39 4 6 39 14 35 35 20
6 40 31 11 6
mean = \boxed{}

Explanation:

Step1: Count the number of data points

We have the data: 39, 4, 6, 39, 14, 35, 35, 20, 6, 40, 31, 11, 6. Let's count them. There are 13 numbers.

Step2: Calculate the sum of the data

Now we sum all the numbers:

$$
LATEXBLOCK0
$$

Step3: Calculate the mean

The mean is the sum divided by the number of data points. So the mean \(=\frac{286}{13}\)

$$ \frac{286}{13}=22 $$

Answer:

22
