Answer143, 132, 149, 148, 151, 146, 135, 128, 139, 150
the height of the tallest boy = I5I cm.
the height of the shortest boy = 128 cm.
the range of the data - — I5I -128 = 23 cm.
the mean height. =
(143 + 132 + 149+ 148 + 151 + 146 + + 128 +139 + 150)/10 = 142.1 cm.
How many boys are there whose heights are less than the mean = 4 boys
