Anabel measured the lengths, in centimetres, of 200 caterpillars. Her results are illustrated in the cumulative frequency graph below.

(i) Estimate the median and the interquartile range of the lengths.

(ii) Estimate how many caterpillars had a length of between 2 and 3.5 cm.

(iii) 6% of caterpillars were of length \(l\) centimetres or more. Estimate \(l\).
