A survey was done regarding the usage of state parks. Out of the 160 people surveyed 100 indicated that they used the park for some form of exercise.
a) Give the point estimate for the population proportion of park users who use the park for exercise. No work is needed.
b) Show all the necessary work by hand in constructing the 98% confidence interval for the true proportion of park users who use the park for exercise. You may round the final endpoints of your interval to the nearest hundredth. Then write an interpretation of your interval in the context of the problem.
