question 111

Essay

The owner of a pet store is trying to decide whether to discontinue selling specialty clothes for pets. She suspects that only 4%
of the customers buy specialty clothes for their pets and thinks that she might be able to replace the clothes with more
interesting and profitable items on the shelves. 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 for their pet.
-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?
