Essay

The owner of a pet store is trying to decide whether to discontinue selling specialty clothes for pets.

Before making a final decision, she decides to keep track of the total number of customers for a day and whether they purchase specialty clothes.
a. The owner had 275 customers that day. Assuming this was a typical day for her store, what would be the mean and standard deviation of the number of customers who buy specialty clothes for their pet each day?
b. Surprised by the high number of customers who purchased specialty pet clothing that day, the owner decided that her 4% estimate must have been too low. How many clothing sales would it have taken to convince you? Justify your answer.
