Q 8: An estimated 80% of undergraduates are employed, according to one research. A fresh group of pupils will be studied in a follow-up research. It is anticipated that they will create a one-sample z interval out of this new data to estimate the percentage of students who are employed. Using a confidence level of 90%, the researchers are aiming for a margin of error of less than ±1%. Which sample size should we use to ensure that the target margin of error is met?
