Construct a frequency polygon of the amounts of Strontium-90. For the horizontal axis, use the midpoints of the class intervals

Question:

Construct a frequency polygon of the amounts of Strontium-90. For the horizontal axis, use the midpoints of the class intervals in the frequency distribution in Exercise 18 from Section 2-2: 110?119, 120?129, 130?139, 140?149, 150?159, 160?169, 170?179, 180?189.

Use the listed amounts of Strontium-90 (in millibecquerels) in a simple random sample of baby teeth obtained from Pennsylvania residents born after 1979 (based on data from ?An Unexpected Rise in Strontium-90 in U.S. Deciduous Teeth in the 1990s,? by Mangano, et. al., Science of the Total Environment).
