The regional transit authority for a major metropolitan area wants to determine whether there is a relationship between the age of a bus and the annual maintenance cost. A sample of 10 busesresulted in the following data.Age of Bus (years) Annual Maintenance Cost (5)13503702222344S5480520590550750800790950(a) Develop a scatter chart for these data. What does the scatter chart indicate about the relationship between age of a bus and the annual maintenance cost?The scatter chart indicates there may be no noticeable linear relationship between age of bus and annual maintenance costThe scatter chart indicates there may be a negative linear relationship between age of bus and annual maintenance cost.O The scatter chart indicates there may be a positive linear relationship between age of bus and annual maintenance cost.(b) Use the data to develop an estimated regression equation that could be used to predict the annual maintenance cost in dollars () given the age of the bus in years (e). What is the estimatedregression model?

(Round your answer to four decimal places.)p-value=State your conclusion.We fail to reject He. We cannot conclude that there is a relationship between age of bus and annual maintenance cost.O We fall to reject Hg. We can conclude that there is a relationship between age of bus and annual maintenance cost.O We reject Ho. We can conclude that there is a relationship between age of bus and annual maintenance cost.We reject Ho. We cannot conclude that there is a relationship between age of bus and annual maintenance cost.What are the correct interpretations of the estimated regression parameters?O is our estimate of the annual maintenance cost when the age of bus is zero years. , is our estimate of the change in annual maintenance cost for a one year increase in age ofbus.O is our estimate of the age of bus when annual maintenance cost is zero. f, is our estimate of the change in age of bus for if one dollar increase in annual maintenance costOis our estimate of the change in annual maintenance cost for a one year increase in age of bus. f, is our estimate of the annual maintenance cost when the age of bus is zeroyears.is our estimate of the change in age of bus for a one dollar increase in annual maintenance cost. , is our estimate of the age of bus when annual maintenance cost is zeroAre these interpretations reasonable?The interpretation of Pox reasonable and the interpretation of Creasonable.X
