11 The frequency table gives information about the weights of 60 parcels.

Weight (\(w\) kg)Frequency
\(0 \lt w \leqslant 2\)7
\(2 \lt w \leqslant 4\)21
\(4 \lt w \leqslant 6\)15
\(6 \lt w \leqslant 8\)11
\(8 \lt w \leqslant 10\)6
(a) Complete the cumulative frequency table.
Weight (\(w\) kg)Cumulative frequency
\(0 \lt w \leqslant 2\)

(b) On the grid below, draw a cumulative frequency graph for your table.
Grid with Weight (w kg) from 0 to 10 on the horizontal axis and Cumulative frequency from 0 to 60 on the vertical axis
(2)
(c) Use your graph to find an estimate for the interquartile range. (2)
(d) Use your graph to find an estimate for the number of these parcels with a weight greater than 7.4 kg. (2)
