Expert Answer

Step 1

Frequency distribution:

Frequency of an interval is the number observations that fall in that interval. The frequency distribution is a table that displays the list of intervals and corresponding frequencies.

Step 2

Find the frequency distribution:

Data represents the body mass index values for 20 females. The lower limit for first class is 15 and the class width is 6.

Table representing classes, observations and corresponding frequencies are given below:
