Answer
Mean = 9
median = 11
Explanation
The reported numbers are: 13, 5, 7, 11, 19
Mean:
[tex]\begin{gathered} Mean=\frac{\sum^x}{N} \\ \sum^x=13+5+7+11+19=45 \\ N=5 \\ \\ Mean=\frac{45}{5}=9 \end{gathered}[/tex]Median:
The median is the middle number either in ascending or descending order:
5, 7, 11, 13, 19
The median is the:
[tex]\frac{N+1}{2}=\frac{5+1}{2}=\frac{6}{2}=3rd\text{ }number[/tex]The 3rd number is 11. Therefore, the median = 11
