Step-by-step explanation:

Answer 2

class length is 5.... because all the classes are in an interval of 5

these are not continuous classes.....

you have to make them continuous by using adjustment factor...

the continuous classes will be...

0.5 to 5.5

5.5 to 10.5

10.5 to 15.5

15.5 to 20.5

class length = upper limit - lower limit = 5.5 - 0.5 = 5
