A statistical program is recommended. A highway department is studying the relationship between traffic flow and speed, The following model has been hypothesiand where - traffic flow in which's per hour Of = vehicle speed in miles per hour The following data were collected during rush hour for six highways leading out of the aty. Traffic Flow Vehicle Speed 1,250 35 1,131 40 1324 1.123 In working further with this problem, statisticians suggested the ure of the foursing orvisan estimated rejoice thaton (a) Develop an estimated regression equation for the diets of the form ? - 4 : fix . /,.. (Round A, to the moose respir modify to tes comal places ned / toured comal pact) (b) Use a = 0.01 to test for a significant feutionthip State the null and alternative hypotheses -H.: One of more of the parameters is not equal to bero.(b) Use a = 0.01 to test for a significant relationship. State the null and alternative hypotheses. ON One or more of the parameters is not equal to zero. Hot One or more of the parameters is not equal to zero, OH. = =0 # : One or more of the parameters is not equal to zero. W: 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 p-value- (Round your answer to three decimal places.) p-value = What is your conclusion? Reject Me. We conclude that the relationship is significant Reject Hor We cannot conclude that the relationship is significant. Do not reject Hoy, We conclude that the relationship is significant. Do not reject He. 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. (Round your answer to two soomal places.) vehicles per hour
