Researchers developed a safety performance 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) = Bo + B1×1 + B2x2, where y = number of crashes per three years, x, =roadway length (miles), and x2 = average annual daily traffic (number of vehicles) = AADT. Click here to view the model results Click here to view a table of critical values of the t distribution. B. This value has no meaningful interpretation because x, =0 and x2 = 0 are not in the observed range. O C. We estimate the mean number of crashes per 3 years will increase by B for each additional vehicle per day, holding roadway mileage constant. Interpret the value of B1. Choose the correct answer below. A. We estimate the mean number of crashes per 3 years will increase by B for each additional vehicle per day, holding roadway mileage constant. B. We estimate the mean number of crashes per 3 years will increase by B for each additional mile of roadway, holding AADT constant. CC. This value has no meaningful interpretation because x, =0 and x, =0 are not in the observed range. Interpret the value of B2. Choose the correct answer below. A. We estimate the mean number of crashes per 3 years will increase by B for each additional vehicle per day, holding roadway mileage constant. B. This value has no meaningful interpretation because x, =0 and x2 = 0 are not in the observed range. CC. We estimate the mean number of crashes per 3 years will increase by B for each additional mile of roadway, holding AADT constant. c. Refer to part a. Find a 98% confidence interval for B,. (Round to five decimal places as needed.)
