- Estimate the 37th percentile.
Given further that the lowest price was \(\pounds 42000\) and the range of the prices was \(\pounds 690000\),
- draw a box plot to represent the data. Show your scale clearly.
In another town the median price was \(\pounds 149000\), and the interquartile range was \(\pounds 90000\).
