Answer 1

Answer:

First the arrange the data in order

1,2,2,2,2,3,3,4,4,5,5,6,6,7,7,8

The largest number =8

The smallest number =1

Range = largest number - smallest number =8−1=7

Hence, we shall calculate an approximate group size, by dividing the range by the number of groups we want.

If we want 3 groups, then Divide range with number of groups =

3

7

=2.333

The class interval width will be 3. Start from 0.

Class interval Frequency

0−3 5

3−6 6

6−9 5

hope this help

Answer 2

Explanation:

frequency                  

0-10                           2                              50

10-20                        12                        50-2=48

20-30                       22                    50-2-12=36

30-40                         8                    50-2-12-22=14

40-50                         6                     50-2-12-22-8=
