i MEDAL AND fAN HELP PLZ
Alex wanted to understand whether grade level had any relationship to their opinion on extending the school day. She surveyed some students and displayed the results in the table below:
In favor Opposed Undecided
Grade 9 5 3 9
Grade 10 8 12 9
Grade 11 15 16 10
Grade 12 12 6 11
Compare P(Grade 12  opposed) with P(opposed  Grade 12).
P(Grade 12  opposed) = P(opposed  Grade 12)
P(Grade 12  opposed) > P(opposed  Grade 12)
P(Grade 12  opposed) < P(opposed  Grade 12)
There is not enough information.
