The EPA has reported that the average fuel cost for a particular type of automobile is $800 with a standard deviation of $80. Fuel cost is assumed to be normally distributed. If one of these cars is randomly selected, what is the probability that the fuel cost for this car exceeds $760?:confused:

Calculate the Z-score: z=(x-mean)/sd; given that Z-score what does your probability table for Z-scores tell you? (hint: the variables x, mean, and sd are all in your question)

Also, note that there's a special forum for homework help so this should have been posted there...
