    Given that a movie producer conducted a survey after a preview screening of her new movie to find out how the film would be received by viewers from different age groups.

    Given the table that shows the numbers of viewers in different age groups who rated the film excellent, good, average, and poor.

    Viewer's Age Group Excellent Good Average Poor Marginal Total

    16-25 52 42 12 7 113

    26-35 33 50 5 9 97

    36-45 58 12 28 34 132

    46-55 25 17 22 12 76

    56 + 12 5 3 8 28

    Marginal Total 180 126 70 70 446

    The number of viewers from the 46 - 55 age group who rated the film excellent is 25.

    Therefore, the percentage of the total survey group who rated the film excellent and also was from the 46-55 age group = 25 / 446 x 100% = 5.61%
