Music and grades (True Story) A couple of years ago a local newspaper published research results claiming a

positive association between the number of years high school children had taken instrumental music lessons

and their performances in school (GPA).

a. What does positive association mean in this context?

b. A group of parents then went to the School Board demanding more funding for music programs as a way to

improve student chances for academic success in high school. As a statistician, do you agree or disagree with

their reasoning? Explain briefly.
