Question

I need help with question 17

Answer 1

`42`

Explanation:

To find the median of a stem and leaf plot, use the equation:

`\begin{gathered} median=(n+1)/(2) \\ where, \\ n=\text{ number of data} \end{gathered}`

Therefore, for the given plot, there are 16 elements.

`\begin{gathered} \text{ median=}(16+1)/(2) \\ \text{ median=8.5} \end{gathered}`

When there are two middle values, the median is the mean of these two values:

`\begin{gathered} (3+1)/(2)=2 \\ \text{ Hence, the median is 42.} \end{gathered}`
