Question 1171233: Studies show that gasoline use for cars is normally distributed, with a mean of 25.5 miles per gallon (mpg) and a standard deviation of 4.5 mpg. What percentage of compacts get
A. less than 24 mpg?
B. 30 mpg or more?
C. between 20 and 28?
This question cannot be answered as posed. You gave the distribution shape, mean, and standard deviation for cars and then asked a question about compact cars, which, presumably have a different distribution with very likely a higher mean for gasoline consumption.
