Question 904010: You are the owner of a small casino in Las Vegas and you would like to reward the high-rollers who come to your casino. In particular, you want to give free accommodations to no more than 10% of your patrons. Suppose that the amount wagered by patrons follows a normal distribution. The mean amount wagered by all patrons is $287 with a standard deviation of $15. You should give free accommodations to those individuals who wager over how much money?
