The lengths of some insects of the same type from two countries, X and Y, were measured. The stem and-leaf diagram shows the results.

i. Find the median and interquartile range of the lengths of the insects from country X.

ii. The interquartile range of the lengths of the insects from country Y is 0.028cm. Find the values of q and r.

iii. Represent the data by means of a pair of box-and-whisker plots in a single diagram on graph paper.

iv. Compare the lengths of the insects from the two countries.
