a) In addition to her car's internal computer calculating miles per gallon, a driver also measured MPG by dividing the miles driven by the number of gallons at fill-up. She wants to determine if these calculations are similar. The data are given in the file MPGDIFF.csv. Consider the driver's MPG calculations as the explanatory variable. Plot the data and describe the relationship. Are there any outliers or unusual values? Does a linear relationship seem reasonable? Run the simple linear regression and record the least-squares regression line. Summarize the results. Does it appear that the computer and driver calculations are the same? Explain your answer. Construct a residual plot. Are there any unusual patterns? Find a 95% confidence interval for the mean response for a driver measured MPG of 39.5. Find a 95% prediction interval for a future response for a driver measured MPG of 39.5
