Answer 1

The interval 44-47 has a frequency of 3 .

The interval 48-51 has a frequency of 4.

The interval 56-59 has a frequency of 1.

The given data set is:

42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59

The number lying in the interval 44-47 are :46, 47, 47

So the interval 44-47 has a frequency of 3.

The number lying in the interval 48-51 are :48, 49, 50, 51

So, the interval 48-51 has a frequency of 4.

The number lying in the interval 56-59 is: 59
