They are easier to read from a greater distance. The Department's hypothesis is that maximum reading distance in feet (Y) decreases as age (X) increases. The proposal, which is going to cost millions of dollars, is supposed to improve highway safety for older drivers. An independent research firm is hired to study the relationship between age and maximum sign legibility distance (in feet). The firm estimates the regression equation below for a sample of 100 drivers ranging in age from 18 to 80.

LaTeX: \hat Y = 590 - 3.4x, with a standard error of the slope for x of .54. The RLaTeX: ^2 = 66.6%

Where LaTeX: \hat Y = distance and x = driver age

What is the predicted maximum sign legibility distance for a person that is 77 years of age?

A. At an age of 77 years, a typical driver will have a maximum reading distance of 328.2 feet.

B. At an age of 77 years, a typical driver will have a maximum reading distance of 590 feet.

C. At an age of 77 years, a typical driver will have a maximum reading distance of 261.8 feet.

D. Not enough information to estimate a prediction.
