where y =B₁ + B₂x + 8 y = traffic flow in vehicles per hour x = vehicle speed in miles per hour. The following data were collected during rush hour for six highways leading out of the city. Traffic Flow Vehicle Speed (y) (x) 1,256 1,331 1,224 1,334 1,350 1,124 35 40 30 45 50 25 n working further with this problem, statisticians suggested the use of the following curvilinear estimated regression equation. ŷ =B₁ + B₂x + B₂x² (a) Develop an estimated regression equation for the data of the form ý = B₁ + B₁x + ₂x². (Round 3 to the nearest integer and to two decimal places and ₂ to three decimal places.)
