City government has collected the following data on annual sales tax collections and new car registrations: a) The loast-squares regression equation that shows the best relationship botween sales tax (in millions) and car registrations (in thousands) is (round your responses to three decimal places and include a minus sign if necessary): y^=+x where y^= Dependebt Variable and x= Independent Variable. b) Using the least-squares regression equation, the estimated sales tax collection when the new number of registrations total is 22,500= a) The least-squares regression equation that shows the best relationship between sales tax (in millions) and car registrations (in thousands) is (round your responses fo three decimal places and inctude a minus sign if necessary): y^=+x where y^= Dependent Variable and x= Independent Variable. b) Using the least-squares regression equation, the estimated sales tax collection when the new number of registrations total is 22,500= 5 million (round your response to two decimal places). c) The coefficient of correlation for the least-squares regression = (round your response to four decimal places). The coefficient of determination for the least-squares regression = (round your response to four decimal places)
