Sales records of a supermarket show that the expenditures of customers during each visit at the supermarket are normally distributed with a mean of $112 and a standard deviation of $36. (a) Find the probability that the expenditure of a randomly selected customer is over $100 during that visit at the supermarket. (b) If 87.7% of customers spent over SK during each visit at the supermarket, find the value of SK. (c) Find the value of Q3 (third quartile) of the expenditures of customers during each visit at the supermarket (d) Suppose 9 customers in the supermarket are randomly selected. Find the probability that exactly 2 of the selected customers spent over $100 during that visit at the supermarket. (i) If it is known that at least 6 of the selected customers spent less than or equals $100 during that visit at the supermarket, find the the probability that at most 2 of the selected customers spent over $100 during that visit at the supermarket.
