MGT 218 The management of a supermarket
The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at the supermarket. The expectation of the management is that after the promotional policy is advertised, the expenditures for all customers at the supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. If the management wants to give free gift to all the customers who spend more than $130, what percentage of the customers are expected to get free gifts ?
