Age (\(n\) years)Cumulative frequency
\(10 \lt n \leqslant 20\) 
\(10 \lt n \leqslant 30\) 
\(10 \lt n \leqslant 40\) 
\(10 \lt n \leqslant 50\) 
\(10 \lt n \leqslant 60\) 
\(10 \lt n \leqslant 70\) 
(b) On the grid below, draw a cumulative frequency graph for your table. (2)
Grid with age in years from 10 to 70 on the horizontal axis and cumulative frequency from 0 to 80 on the vertical axis
(c) Use your graph to find an estimate for the percentage of the 80 people who are more than 46 years of age.
