It was found that from a sample of students from an introductory statistics course, which has 50 students enrolled, 15 of these students planned to take higher level statistics courses. There are several statistics courses with an entirety of 300 students in all these courses together. We want to estimate the number of students who are going to take higher level statistics courses with a 0.95 confidence level.
