You want to obtain a sample to estimate a percentage of Statistics students at ACM that get a grade of at least a C. You would like to be 90% confident that your estimate is within 1.5% of the true population proportion. a) You have no reasonable estimate for the population proportion. You do not know the number Statistics students at ACM. How large of a sample size is required? b) You estimate the population proportion to be 90 percent. You do not know the number Statistics students at ACM. How large of a sample size is required? c) You have no reasonable estimate for the population proportion. You know that there is a total of 800 Statistics students at ACM. How large of a sample size is required? d) You estimate the population proportion to be 90 percent. You know that there is a total of 800 Statistics students at ACM. How large of a sample size is required?
