(i) Draw a box-and-whisker plot on a linear scale (thousands of dollars). Mark the lower quartile, median, upper quartile, and whisker endpoints correctly.

(ii) Compute the interquartile range (IQR) and the outlier fence:
Lower quartile: \(Q_1 = 538\), Upper quartile: \(Q_3 = 690\).
\(\text{IQR} = Q_3 - Q_1 = 690 - 538 = 152\).
\(\text{Upper fence} = Q_3 + 1.5\,\text{IQR} = 690 + 1.5\times 152 = 918.\)
Any price \(> 918\) is “expensive”. Hence the expensive houses are \(957\) and \(986\) (thousands of dollars).

(iii) A box-and-whisker plot does not display individual data values, so detailed distribution features (like gaps or clustering) are hidden.
