The cumulative frequency function of the data below is given below by the equation y = cf(x). What is cf(5)? Score(n)Frequency(f)330432530635820

The cumulative frequency function of the data below is given below by the equation y = cf(x). What is cf(5)?

$\begin{array}{cc}Score\left(n\right)& Frequency\left(f\right)\\ 3& 30\\ 4& 32\\ 5& 30\\ 6& 35\\ 8& 20\end{array}$

Answer Details

If y = cf(x)
cf(5) = 30 + 32 + 30
= 92
