A simple random sample of 400 individuals provides 100 Yes responses. a. What is the point estimate of the proportion of the population that would provide Yes responses (to 2 decimals)? b. What is your estimate of the standard error of the proportion (to 4 decimals)? c. Compute the 95% confidence interval for the population proportion (to 4 decimals).

Step 1
Point Estimate: The point estimate of the proportion is simply the sample proportion. In this case, it is the number of Yes responses divided by the total number of responses. So, 100/400 = 0.25. Therefore, the point estimate of the proportion is 0.25. Show more…
