Español The Ellington Dukes are a minor-league baseball team in Ellington, Georgia. As with most other minor-league teams, the Dukes rely heavily on promotions to bring fans to the ballpark. These promotions are typically aimed at fans of specific ages.

A statistical consulting firm for the Dukes surveyed a random sample of 150 fans attending Dukes games in order to see if these estimates are accurate. For the sample of 150, the observed frequency of each age category is given in the top row of numbers in the table below. The second row of numbers contains the frequencies expected for a random sample of 150 fans if the Dukes' management's estimates are accurate. The bottom row of numbers contains the following value for each of the age categories. Aa (Observed frequency - Expected frequency ) fE Expected frequency Part 1
