Tab (b) Use a = 0.01 to test for a significant relationship. State the null and alternative hypotheses. O Ho Bo=B1-B2=0 H: One or more of the parameters is not equal to zero. ọ Ho: Bí = B2 = 0 H: One or more of the parameters is not equal to zero. O Ho: One or more of the parameters is not equal to zero. O Ho: One or more of the parameters is not equal to zero. Ha Bo B₁ =B2=0 Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value= What is your conclusion? O Do not reject H. We conclude that the relationship is significant. O Reject Ho. We cannot conclude that the relationship is significant. O Reject Ho. We conclude that the relationship is significant. O Do not reject Ho. We cannot conclude that the relationship is significant. (c) Base on the model predict the traffic flow in vehicles per hour at a speed of 38 miles per hour.

V All Ctri D A statistical program is recommended. A highway department is studying the relationship between traffic flow and speed. The following model has been hypothesized: where y= B₁ + B₁x+ 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.
