Answer fast for pts

Maria wants to know the average arrival time
of the students at her school. She arrives one
morning at 8:30 a.m. and records the arrival
times of the students that arrive between
8:30 a.m. and 9:00 a.m. Explain why Maria's
sample is not a representative sample.

Answer 1

• Maria arrived at 8:30
• It's can't be told that no one have arrived before her
• She registered the times between 8:30 to 9:30 .
• She hasn't registered the data of students who came before her .
• So it's not a representative sample

Answer 2

Since she arrived at 8:30 its not accurate because her records started at the time she arrived so she didnt get the times of the students that arrived before her
