Question

A highway department is studying the relationship between traffic flow and speed. The following model has been hypothesized.

y = B₀ + B₁x + e

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 ( )
1294		40
1332		45
1300		40
1233		30
1334		45
1129		25

a. Develop an estimated regression equation for the data.

the regression equation is:

y = [          ] + [              ] X ( to 2 decimals )

b. Use to test for a significant relationship.

S= [     ? ]

R² = .9443

R-sq adj = .9304
