question 124

Essay

The owner of a small convenience store is trying to decide whether to discontinue selling magazines. He suspects that only
5% of the customers buy a magazine and thinks that he might be able to use the display space to sell something more
profitable. Before making a final decision he decides that for one day he'll keep track of the number of customers and
whether or not they buy a magazine.
-Surprised by a high number of customers who purchased magazines that day, the owner
decided that his 5% estimate must have been too low. How many magazine sales would it
have taken to convince you? Justify your answer.
