Question: A national survey claims that people buy music compact disks in equal percentages for the following five age groups: 14 -18, 19 - 23, 24 - 28, 29 - 33, and over 33. A sample of the ages of 100 CD buyer's at Hastings, on Fry Blvd, gave these data: 15, 21, 18, 30, and 16, for the sequence of age groupings, respectively. At "alpha" = 0.01 can we conclude that the local numbers are the same as the national survey?
