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

Error range

$=\pm 8%$

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,

Option B: 62%
