The U.S. government has been interested in pushing auto manufacturers to increase the MPG of their fleet.

Based on the information above, what proportion of the SUVs are 8 cylinder vehicles (I want the proportion and not the percentage)? I just want the numerical answer. Use 4 decimal places and use the proper rules of rounding.
Based on the regression results, solve for the predicted MPGavg for 4 cylinder cars. I just want the numerical answer. Use 4 decimal places and use the proper rules of rounding.
