Question 976394: The average price of a used car is $6500 with a standard deviation of 850. If the prices are approximately normally distributed, find the minimum and maximum prices that includes the middle 75% of these prices. Answer by FrankM(1040) (Show Source):
You can put this solution on YOUR website! A Z score of +/- 1.15 will include 75%. $850*1.15 = $977.50
$6500+/- $977.50 =
Max = $7477.50
Min = $5522.50
