A research firm conducts a study to explore the relationship…
A reseаrch firm cоnducts а study tо explоre the relаtionship between a driver’s age and the driver’s ability to read highway signs. The subjects are a random sample of 30 drivers between the ages of 18 and 82. (Source: Jessica M. Utts and Robert F. Heckard, Mind on Statistics [Brooks/Cole, 2002]. Original source: Data collected by The Last Resource, Inc., Bellfonte, PA.) Suppose we want to predict the maximum distance at which a 90-year-old driver can read a highway sign. The prediction for a 90-year-old driver is 306 feet. y = – 3*(90) = 306 feet (Sign Legibility Distance = Max distance to read sign) Which of the following interpretations are valid? The prediction is an example of extrapolation because drivers in the original data set ranged in age from about 18 to 82. [dropdown1]
