Question

Give full steps solution ..

Answer 1

no.of workers-45
daily wages - 100. 120. 150. 170. 200
frequency. - 6. 8. 9. 12. 10
FX=frequency × wage
=100×6=600...and so on
FX - 600,960,1350,2040,2000
sum of FX=6950
sum of f=6+8+9+12+10=45

formula for finding mean=sum of fx÷sum of f
=6950÷45
=154.44444

therefore the mean=154.44

Answer 2

no of worker=45
fervency of wages=6,8,9,12,10
fx=f*x
fx=6950
mean=fx/sum of f
=6950/45
=154.44

mean=154.44
median=150
