Question

Need help solving this problemNote for part A I got 4/22 and it was incorrect

Answer 1

First, we need to find the total frequency. This is given by adding all the given frequencies. That is,

`\begin{gathered} f_{\text{total}}=4+6+7+5 \\ f_{\text{total}}=22 \end{gathered}`

and the relative frequency is the division of the frequency of the corresponding interval by the total frequency,

`f_{\text{rel}}=\frac{f_{\text{ interval}}}{f_(total)}`

Therefore, the answers are:

a) 4/22 but written in simple form:

`(2)/(11)`

b)

`(5)/(22)`
