Question: Suppose that county planners are interested in learning about the proportion of county residents who would pay a fee for a curbside recycling service if

Suppose that county planners are interested in learning about the proportion of county residents who would pay a fee for a curbside recycling service if the county were to offer this service. Two different people independently selected random samples of county residents and used their sample data to construct the following confidence intervals for the proportion who would pay for curbside recycling: Interval 1: ( 0.68, 0.74) Interval 2: ( 0.68, 0.72)
a. Explain how it is possible that the two confidence intervals are not centered in the same place.
b. Which of the two intervals conveys more precise information about the value of the population proportion?
c. If both confidence intervals are associated with a 95% confidence level, which confidence interval was based on the smaller sample size? How can you tell?
d. If both confidence intervals were based on the same sample size, which interval has the higher confidence level? How can you tell?
