Step-by-step explanation:

A correct option is option (A).

Stem Leaf Plot:

The Stem and Leaf plot is a way of organizing data into a form that makes it easy to see the frequency of different values.

Consider the given, data for the miles per gallon rating for 30 cars.

The steps to create a stem plot are written below:

  • Divide each observation of data into stem and leaf.
  • Write the stems in a vertical line from smallest to largest
  • Draw a vertical line to the right of the stems.
  • Write the leaves in increasing order next to their corresponding stem.

For the given data the stem plot is constructed as shown below:

1.9 9 9

2.0 1 1 5 5 5 6 6 8 9

3.1 1 2 2 3 4 5 6 7 7 8 8 8 8

4.1 3 3

5.6 1

From the above stem plot, it is observed that most of the miles per gallon rating values appear to concentrate at the 30s and 20s.

There is no out liter in the given data.
