b. which value(s) of produce(s) the least variability in sample proportions?

9. Without doing more calculations, describe whether, and if so, how your answers to parts a and b might change using a sample size of 500 rather than 1000 people:

0The answers to parts a and b would both increase

0 The answers to parts a and b would both decrease

0 The answers to parts a and b would all remain the same

0The answers to part a would decrease, while the answers to part b would remain the same

Presidential Approval
Let TT represent the population proportion of adult Americans who respond favorably
when asked about the president's job performance. Suppose you repeatedly take
simple random samples (SRSs) of 1000 adult Americans and determine the sample
proportion who respond favorably.
a. Use the Central Limit Theorem to calculate the standard deviation of the sampling
distribution of these sample proportions for each of the following values of TT. Round
standard deviations to 5 decimal places if necessary.
Round your answers to five decimal places.
If π = 0, the sampling standard deviation is ____
