Grouped Data

23.      Grouped Data: Shoplifting What is the age distribution of adult shoplifters (21 years of age or older) in supermarkets? The following is based on information taken from the National Retail Federation. A random sample of 895 incidents of shoplifting gave the following age distribution:

 

Age range (years)

21–30

31–40

41 and over

Number of shoplifters
