Given : x,y and z are observations and the sum of their frequencies is 50 and relative frequencies corresponding to x and z are 30% and 40% respectively.
To Find :
a) what is the frequency corresponding to y?
b) what will be the cumulative frequency of x and z?
Solution:
x + y + z = 50
relative frequencies of x = (x/50) * 100 = 30
=> x = 15
relative frequencies of z = (z/50) * 100 = 40
=>z =20
frequency corresponding to y = 50 - 15 - 20
= 15
cumulative frequency of x and z = 15 + 20 = 35
