Icollect a random sample of size n from a population and compute a 95% confidence interval for the proportion i observe from the population. what could i do to produce a new confidence interval with a smaller width, smaller margin of error, based on these same data?

You should increase the size of your random sample, that is, increase the value of n.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.

In which

z is the zscore that has a pvalue of .

The margin of error is:

This means that as we increase the sample size(n), the margin of error decreases, as does the width of the confidence interval.

What could I do to produce a new confidence interval with a smaller width, smaller margin of error, based on these same data?
