Two comparable cars of BMW and Mercedes are BW 330 cci and the Mercedes CLK 320. As of 2006, the average manufacturer's suggested retail price for a 330 cci was $37600 as compared to the $45750 for a CLK 320. The dealer prices however are not consistent. The dealer prices for CLK 320 follow a normal distribution with a mean of $45750 and a standard deviation of $2981. The dealer prices for 330 cci are normally distributed with a mean of $37600 and a standard deviation $2367. What percentage of BMW dealers are pricing the 300 cci at more than the average price for a CLK 320? What percentage of Mercedes dealers are pricing a CLK 320 less than the average price of a 330 cci?

The gas mileage rates for various CLK cars are uniformly distributed over a range from 24 miles per gallon (mpg) to 34 mpg. What proportion fall between 26 to 30 mpg range? Gas mileage rates for 330 cci are uniformly distributed between 25 mpg to 35 mpg? What proportion of 330 cci cars fall between 26 to 30 miles per gallon range? Compute the percentage of each of the car models that get 30 or more mpg.
