Question

Fit a binomial distribution of the following- class 15-19, 20-24, 25-29, 30-34, 34-39, 40-44/ frequency. 13, 32, 04, 42, 58, 51 full solution

Answer 1

Answer:

correct class distribution goes like this

Step-by-step explanation:

15.5-20.5

20.5-25.5

25.5-30.5....

Answer 2

A binomial distribution of the following is as follows.

class              frequency

15 - 19                    13

20 - 24                  32

25 - 29                  04

30 - 34                   42

34 - 39                   58

40 - 44                   51

From given class interval we have,

Gap = 20 - 19 = 1

Gap/2 = 1/2 = 0.5

we need to add the Gap/2 to upper limits and subtract Gap/2 from lower limit to make it as continuous function.

Therefore, we have,

class                   frequency

14.5 - 19.5                   13

19.5 - 24.5                  32

24.5 - 29.5                  04

29.5 - 34.5                   42

34.5 - 39.5                   58

39.5 - 44.5                   51
