The heights of 50 students, measured to the nearest centimetres, have been found to be as follows:
$161162153154161150164159152159154171161153162165165170156167168158162158168161154165162159154156166160158162172168161153150160165173154151170164166159$

(i) Represent the data given above by a grouped frequency distribution table, taking the class intervals as $160 - 165, 165 - 170,$ etc.
(ii) What can you conclude about their heights from the table?
