A study examined the maximum distance (y, in feet) at which a driver can read a highway sign and the age (x, in years) for a random sample of 30 drivers. A scatterplot of the data shows a linear association between the two variables. Below is software output for a linear regression analys using these data:

Predictor, Coef, SE Coef, T, P, 95% CI
Constant, 576.68, 23.47, 24.57, 0.000, (528.60, 624.76)
Age,

Solution

a) Give the equation of the least-squares regression line estimating maximum viewing distance as a function of driver age.

y=576.68
