Answer 1

Answer:

Given : 31, 23, 19, 29, 22, 20, 16, 10, 13, 34, 38, 33, 28, 21, 15, 18, 36, 24, 18, 15, 12, 30, 27,  25, 20, 17, 14, 32, 26, 25, 18, 29, 24, 19, 10, 11, 22, 15, 17, 10​

To Find : Form a grouped frequency distribution by inclusive method taking 4 as the  magnitude of class intervals.

Solution:

Arranging in order

10 10 10 11 12 13 14 15 15 15 16 17 17 18 18 18 19 19 20 20 21 22 22 23 24 24 25 25 26 27 28 29 29 30 31 32 33 34 36 38

inclusive  class intervals. - Lower and upper both limits are included  for data

Class        Frequency

9  - 12        5         ( 10 , 10 , 10 , 11 , 12)

13 - 16        6        (   13 14 15 15 15 16  )

17 - 20       9       (  17 17 18 18 18 19 19 20 20 )

21 - 24        6       ( 21 22 22 23 24 24)

25 - 28       5       ( 25 25 26 27 28 )

29 - 32        5     ( 29 29 30 31 32 )

33 - 36        3     (  33 34 36     )

37 - 40        1       ( 38 )        

Total         40
