Answer 2

Answer:

Lower class boundary for class 14 -19 is 13.5

Step-by-step explanation:

In the frequency table 8- 13, 14 -19 , 20 - 25 .....

Here the class intervals are not continuous .

To make them continuous take the mean of upper limit of first class lower limit of second class.

Mean =(13 +14 )/2 = 27/2 =13.5 which gives the lower limit of second class and upper limit of first class for the continuous class interval.
