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. The management for the Dukes has planned its current promotional schedule according to the following estimates: 15% of fans attending Dukes games are ages 0 to 12, 10% are ages 13 to 18, 30% are ages 19 to 35, 25% are ages 36 to 55, and 20% are over 55. A statistical consulting firm for the Dukes surveyed a random sample of 200 fans attending Dukes games in order to see if these estimates are accurate. The observed frequencies in the sample of 200 for each of the age categories are given in the top row of numbers in Table 1 below. The second row of numbers contains the frequencies expected for a random sample of 200 fans if the Dukes' management's estimates are accurate. The bottom row of numbers in Table 1 contains the values (Observed frequency - Expected frequency)? Expected frequency fE for each of the age categories. Fill in the missing values of Table 1. Then, using the 0.10 level of significance, perform a test of the hypothesis that the management's estimates are accurate. Then complete Table 2. responses in Table 1 to at least three Round your responses for the expected frequencies in Table 1 to at least two decimal places. Round your decimal places.
