In order to use Table A, a standardized amount of money spent by shoppers should be calculated. For a shopper who spends $47 during one visit to Wainwright’s, this standardized amount of money equals z = (47 – 50) / 10 = -0.3. The cumulative proportion for z is 0.3821. This means that the probability that shoppers will spend less than $47 during their next visit to Wainwright’s is 0.3821.
