The correlation between Fuel Efficiency (as measured by miles per gallon) and Price of 150 cars at a large dealership is r = -0.34. Explain whether or not each of these possible conclusions is justified:
a) The more you pay, the lower the fuel efficiency of your car will be.
b) The form of the relationship between Fuel Efficiency and Price is moderately straight.
c) There are several outliers that explain the low correlation.
d) If we measure Fuel Efficiency in kilometers per liter instead of miles per gallon, the correlation will increase.
