Answer 1

Answer:

Weight  No. Of Students(x)        xf            cf

47                  4                             188             4

50                 3                              150            7

53                 7                              371             14

56                 2                              112             16

60                 4                              240           20

266                                              1061

Then, mean =  

Σx

Σxf

​  

=  

266

1061

​  

=3.99

Here, N=20 then  

2

20

​  

=10

In the table, cumulative frequency greater then 10 is 14 where value of x=53

Then, median is 53

In the given table, greatest frequency is 7 where value of x=53 then mode is 53.
