You own a small storefront retail business and are interested in
determining the average amount of money a typical customer spends
per visit to your store. You take a random sample over the course
of a month for 9 customers and find that the average dollar amount
spent per transaction per customer is $113.075 with a standard
deviation of $15.4543. Create a 95% confidence interval for the
true average spent for all customers per transaction.
