As part of a study on transportation safety, the U.S. Department of Transportation collected dataon the number of fatal accidents per 1000 licenses and the percentage of licensed drivers underthe age of 21 in a sample of 42 cities. Data collected over a one-year period follow. These dataare shown in the table below.PercentFatal AccidentsPercentFatal AccidentsUnder 21per 1000 LicensesUnder 21per 1000 Licenses132.962174.1120.70882.198.0.885163.623121.652152.623112.09190.835172.62780.82183.83142.898.0.36881.267131.142153.2248.0.645101.0141.028100.493162.801141.443121.405183.6149.1.433101.926100.039141.6439.0.338162.943111.849121.913122.246152.814142.855132.634142.3529.0.926111.294173.256Managerial Reporta.
