Answer 2

Step-by-step explanation:

Daily wages No. of workers class mark(xi)

100-120 12 110

120-140 14 130

140-160 8 150 =a

160-180 6 170

180-200 10 total=50 190

di=xi-a fidi

-40 -480

-20 -280

0 0

20 120

40 400

total=-240

£fidi=-240

£fi=50

a=150

Assumed mean method,

x= a+£fidi/£fi

x= 150+(-240)/50

x=150-240/50

x=150-4.8

x=145.2

Therefore,mean is 145.2

hope this help you!!!!!
