consider the data set shown below.
42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59
to create a histogram of the data given, identify the
frequency for the given intervals.
the interval 44-47 has a frequency of ______.
the interval 48-51 has a frequency of ______.
the interval 56-59 has a frequency of ______.

Explanation:

Step1: Count 44-47 values

Data in 44-47: 46, 47 → Count = 2

Step2: Count 48-51 values

Data in 48-51: 48, 49, 50, 51 → Count = 4

Step3: Count 56-59 values

Data in 56-59: 59 → Count = 1

Answer:

The interval 44-47 has a frequency of 2.
The interval 48-51 has a frequency of 4.
The interval 56-59 has a frequency of 1.
