Look at how we construct a confidence interval for a population proportion. One thing to notice is the effect of sample size on standard error

n

which will effect the length of the confidence interval.Larger sample sizes will lead to smaller standard errors.

Is the following: True or False?

All other things being equal in constructing a confidence interval for a population proportion, the confidence interval constructed using a sample size of n = 500 as compared to n = 200 will be a better estimate for the population proportion. That is, the confidence interval will have a shorter length.
