Question

Find the lower quartile for the distribution
Wages: 0-10 10-20 20-30 30-40 40-50
No. of Workers 22 38 45 35 20

Answer 1

Answer:

24.46

Step-by-step explanation:

N=161

Here=N/2=161/2

=80.05 Median is 20-30

l (lower limit)=20

f (Frequency)=46

cumulative frequency median(m)=60

Width of class (c)=10

Median=lower limit +161/2-cumulative median/frequency*width of class

=20+80.5-60/46*10

=20+10/46*20.5

=20+205/46

=20+4.46

=24.46

Median=24.46
