Hello! I'm having trouble with this practice question. I basically went through the entire problem, but every result was incorrect. So all of my calculations are incorrect.

A highwayr department is studying the relationship between traffic ow and speed. The following model has been hypothesized: y = 80 + 191:: + 5 where y = tlaic ow 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. 1,255 35 1,328 40 1,225 30 11337 45 1,343 50 1,123 25 In working further with this problem, statisticians suggested the use of the following curvilinear estimated regression equation. 1? = tan +b1x+b2x2 (3} Develop an estimated regression equation for the data of the form ,9 = bu + blx + bzxz. {Round b0 to the nearest integer and bl to two decimal places and 72 to three decimal places.) p: (In) Use as = 0.01 to test for a signicant relationship. State the null and alternative hypotheses. O H\": One or more of the parameters is not equal to zero. Ha:b0=b1=b2=0 O H\": .51 = 52 = 0 Ha: One or more of lhe parameters is not equal to zero. 0 HI]: One or more of the parameters is not equal to zero. Hi: (:1 = :52 = D O Hu:bo=b]_=b2=0 Ha: One or more of the parameters is not equal to zero. Find the value of the test statistic. (Round your answer to two decimal places.) Find the ovalue. {Round your answer to three decimal places.) p-vaiue = What is your conclusion? 0 Do not rejed Ho. We conclude that the relationship '6 signicant. 0 Reject Ho. We cannot conclude that the relationship is signicant. 0 Reject \"0' We mndude lat the relationship is signicant 0 Do not reject Ho. We cannot wndude that the relationship is signicant. (c) Base on the model predid: the trafc ow in vehicles per hour at a speed of 38 miles per hour {Round your answer to two decimal places.) vehides per hour
