Answer:
20
Step-by-step explanation:
To find the mean, add up all the numbers in the data set, and then divide by the number of terms in the data set
<em>Add </em>
Add up the numbers in the data set
17+24+26+13
80
<em>Divide </em>
Divide by the number of terms in the data set
In this case, there are 4 terms (17, 24, 26, 13)
80/4=20
The mean of the data set is 20
