Question
The head of a computer science department is interested in estimating the proportion of students
entering the department who will choose the new computer engineering option. A preliminary sample
indicates that the proportion will be around 0.25. Therefore, what size sample should the department
head take if she wants to be 95% confident that the estimate is within 0.10 of the true proportion?
