Problem
The heights (in cm) of 20 saplings planted in a school garden are:
42, 45, 47, 46, 44, 45, 48, 49, 45, 47, 46, 48, 45, 44, 46, 47, 45, 49, 46, 48
Answer the following questions.
(a) Find the mode of the given data and state its frequency.
(b) If the tallest sapling (49 cm) is uprooted and removed from the list, determine the new mode and its frequency.
(c) Comment on whether removal of a single extreme observation necessarily changes the mode of a data set, using your results from parts (a) and (b).
