He collects data on a variety of makes and models of cars. The scatterplot shows that a linear model is appropriate. SPSS output is provided below. -Calculate a 98% confidence interval for the average fuel efficiency for all cars that hold 18 gallons of fuel. Descriptive statistics for the two variables are provided below. Use the mean to obtain \overline{x} and the variance to calculate . Use these two values then to calculate s.e.(fit).
