Question

in a recent survey of students who graduated From a large public highl school , nine out of ten students reported that they passed biology with a grade of 75% or higher. What further data could be produced to be sure that this information is accurate?

Answer 1

No , this information is a two sided prop because we can not interfere in both sides

Answer 2

A review of the student's school transcripts can verify the accuracy of the information.

Using this, the surveyor can genuinely figure out whether 9 out of 10 students have got the grades as stated in the survey. 

The other options are not relevant.

A survey of students from nearby schools doesn't add to the accuracy of the results.

Consulting students parents also might not be helpful as parents often do not know how well their children are performing.
