Researchers developed a safety function (SPF), which estimates the probability of occurrence of a
crash for a given segment of roadway. Using data on over 100 segments of roadway, they fit the model
E(y) 0+x+x where y=number of crashes per years, x =roadw

a. The average (mean) annual income was less than $50,000
