Question

solve the given questions in a paper step by step

Answer 1

.
.
Converting the given distribution to a less than type cumulative frequency distribution , we get

Daily Income ( in c ) and
(Number of Workers )
< 120. ................12.

< 140. ...............12 + 14 = 26

< 160. ..............26 + 8 = 34

< 180. .................34 + 6 = 40

< 200. .............40 + 10 = 50

Let's now plot the point corresponding to the ordered pairs ( 120, 12 ) , ( 140 , 26 ) , ( 160 , 34 ) , ( 180 , 40 ) and ( 200 , 50 ) on graph paper and join them by a free hand smooth curve.
