Question

11. In a frequency distribution, the mid-value of a class is 20
and the width of the class is 8. then the lower limit of the class is​

Answer 1

Answer:

16 is the lower limit

Step-by-step explanation:

! The mid value = class mark

! then divide the total range by 2 to find the number of value after and before the class mark ----------a

! then add the number to the class mark to get the upper limit and subtract from the mark to get the lower limit.---------b

! Thus 8/2 = 4 (a)

!  20+4 == upper limit = 24

!  20-4 =  lower limit = 16
