A) 35.6
B) 33.1
C) 30.3
D) 28.1
Correct Answer: B
Solution :
Given: Width of each of 9 classes = 2.5 Total width of 9 classes \[=9\times 2.5=22.5\] Lower class boundary of lowest class =10.6 \[\Rightarrow \]The upper class boundary of highest Class = lower class boundary of lowest Class + Total width =10.6 + 22.5 = 33.1 Hence, the required upper class boundary =33.1.You need to login to perform this action.
