Question

a.19.5-29.5
b.19.75-29.75
c. 20-30
d 19-29​

Answer 1

Answer:

a.19.5

Step-by-step explanation:

10−19,20−29,30−39,...

Here the class intervals are not continuous. To make them continuous take the mean of upper limit of first class and lower limit of second class.

Mean =

2

19+20

=19.5, which gives the upper limit of first class and lower limit of second class for the continuous class intervals.
