Two students are in charge of finding how many T-shirts to order for the students that want one. Each student collects sample data. The conclusions are shown. Compare the students' conclusions. Whose inference do you agree with? Explain. If there are 504 students in the school, use the better conclusion to estimate the number of T-shirts the school should order.
Student 1: Simple random sample; StartFraction 35 Over 50 EndFraction
said they would like a T-shirt, so order enough for 70% of the school.
Student 2: Systematic sample; StartFraction 51 Over 60 EndFraction
said they would like a T-shirt, so order enough for 85% of the school.
