A city in the Pacific Northwest recorded its highest temperature at 91 degrees Fahrenheit and its lowest temperature at 12 degrees Fahrenheit for a particular year. Use this information to find the upper and lower limits of the first class if you wish to construct a frequency distribution with 10 classes

• 12 - 19

• 12 - 20

• 12 - 18

What are some benefits of representing data sets using frequency distributions?

• Organizing the data into a frequency distribution makes it possible to graph quantitative data

• It is easier to determine the minimum and maximum values of a data set when it has been arranged into a frequency distribution

• Organizing the data into a frequency distribution can make patterns within the data more evident.

Use the frequency histogram to answer each question.
