Question

find the mean of 3, 5, 9, 6, 4, 9 graphically.
3 + 5 + 9 + 6 + 4 + 9 = 36
what is the average value?
answer attempt 1 out of 2
you must answer all questions above in order to submit.

Explanation:

Step1: Recall mean formula

The mean $\bar{x}$ of a set of numbers $x_1,x_2,\cdots,x_n$ is $\bar{x}=\frac{\sum_{i = 1}^{n}x_i}{n}$, where $\sum_{i=1}^{n}x_i$ is the sum of the numbers and $n$ is the number of data - points.

Step2: Identify sum and number of data - points

We are given the numbers 3, 5, 9, 6, 4, 9. The sum $\sum_{i = 1}^{6}x_i=3 + 5+9 + 6+4 + 9=36$, and the number of data - points $n = 6$.

Step3: Calculate the mean

$\bar{x}=\frac{36}{6}=6$
