Answer:

median: 9

mean: 9.4

Step-by-step explanation:

To find the median, we need to organize the values from lowest to greatest, so

6, 7, 9, 12, 13

Then, the median will be the value that divides the data into two equal parts. In this case, is 9 because there are two values to the left of 9 and two values to the right of 9.

Therefore, the median is 9

On the other hand, the mean is calculated as the sum of all the values divided by the total number of values. Then


\begin{gathered} \operatorname{mean}=(6+7+9+12+13)/(5) \\ \text{mean}=(47)/(5) \\ \text{mean}=9.4 \end{gathered}

Therefore, the answers are:

median: 9

mean: 9.4
