Question

if 1-10 11-20 21-30 are the classes the upper limit of the class 11 -20 is​

Answer 1

upper limit of class 11 - 20  is   20.5  if  1-10 11-20 21-30 are the classes

Step-by-step explanation:

1-10 11-20 21-30 are the classes

as we can see there is a difference of  1  between upper limit of prevoius class & lower limit of next classs

These are inclusive class intervals

and we need to convert then in Exclusive class interval

Then class boundaries would be

0.5  - 10.5

10.5 - 20.5

20.5 - 30.5

11 - 20 is converted into 10.5 - 20.5

where 20.5 is not included ( 20.5 is excluded)

Hence upper limit of class 11 - 20  =  20.5
