Answer:
18.6
Step-by-step explanation:
To find the mean of a data set, first, you have to arrange the numbers from least to greatest. Since the data set is already in that order, this saves us the first step. Next, what we would do is add up the numbers...
13+16+17+19+22+25=...
112.
Next, we would have to divide that number by 6 because there are 6 numbers. 112 ÷ 6 = 18.666666666666666666666666666667
Rounded to the nearest tenth, it would be 18.6
Therefore, the mean of this data set is 18.6.
