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:

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

Step-by-step explanation:

Hope this helps:))

  • 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
