5. In a random sample of 200 adult Americans, 8 had some form of color blindness.
a. Construct and interpret a 95% confidence interval using the Wilson-adjusted method.
b. Using the information above as a pilot study, how many adult Americans would need to be sampled in order
to estimate the population proportion with a standard error of no more than 0.005?
c. If no prior estimate of the prevalence of color blindness was available, how many adult Americans would
need to be sampled in order to estimate the population proportion with a standard error of no more than
0.005?
