Suppose that you wanted to determine a confidence interval for the number of people who

will get the influenza vaccine. You construct a 95% confidence interval and find a point

estimate of 128,228 and a margin of error of 5400.



a. What are the requirements necessary for finding this confidence interval. Assume

that we do NOT know the standard deviation for the population.
b. What interval would you construct (z-interval, t-interval or proportion interval)?

Assume you do NOT know the population standard deviation.
c. Construct the confidence interval.
