Answer
Class Interval Frequency cf
100-110 6 6
110-120 35 41
120-130 48 89
130-140 72 161
140-150 100 261
150-160 4 265
Median =
N = 265
median class =
(265+1/2) = 133
therefore modal class = 13-140
L = lower class limit
130 + {(265/2) + 89/265 * 10}
130 + 132.5+89/53 * 2
130 + 221.5/26.5
130(26.5) + 221.5/26.5
