Answer 1

To create a stem plot of the highest temperature readings in degrees Fahrenheit for Phoenix, Arizona for each day in July 2013, follow these steps: list the data in increasing order, write the first digit of each number as stems, write the second digit as leaves, align the leaves for each stem, and provide a key for interpretation.

Step-by-step explanation:

To create a stem plot of the highest temperature readings in degrees Fahrenheit for Phoenix, Arizona for each day in July 2013, follow these steps:

1. List the data in increasing order.
2. Write the first digit of each number in a vertical column on the left side of the page. These digits are called the stems.
3. Write the second digit of each number to the right of the corresponding stem. These digits are called the leaves.
4. If there is a number that ends in a decimal, such as 100.5, round the number to the nearest whole number and treat it as a regular number, using the rounded value for the leaf.
5. Align the leaves for each stem vertically.
6. Write a key that explains the stems and leaves.

For example, if the highest temperature readings for each day in July 2013 were 100, 102, 105, 107, and 109, the stem plot would look like this:
10 | 0
10 | 2
10 | 5
10 | 7
10 | 9
