  1. Answer with explanation:

    Percentage of population of a resident of town who favor expanding the park and recreation department= 68 %

    Error range

            [tex]=\pm 8%[/tex]

    Confidence level =95 %

    As error range is from -8% to +8%.

    So, →→ 68 -8=60% ≤Population Range ≤ 68+8=76%

    →→60% ≤Population Range ≤76%

    Among the four percentages of the town's residents who favor expanding the park and recreation department that lie in the above Population Range is,
