(Solution Download) Does a simple linear model appear to be appropriate? Explain.

A study of emergency service facilities investigated the relationship between the numberof facilities and the average distance traveled to provide the emergency service. Thefollowing table gives the data collected.Number of Average DistanceFacilities (miles)9 1.6611 1.1216 .8321 .6227 .5130 .47a. Develop a scatter diagram for these data, treating average distance traveled as thedependent variable.b. Does a simple linear model appear to be appropriate? Explain.c. Develop an estimated regression equation for the data that you believe will bestexplain the relationship between these two variables.
