Russell surveyed 16 students at his school and found that 4 of them planned to take orchestra as their next elective. If Russell surveys 12 more students, how many of them are probably planning on taking orchestra as an elective, based on past data?
students
Based on the past data, if 4 out of 16 students planned to take orchestra as their next elective, it can be estimated that approximately 1/4 of students are interested in taking orchestra.
If Russell surveys 12 more students, a rough estimate would be that 25% of those students, or 3 students, may be planning on taking orchestra as an elective based on past data.
