Question 1
1.
60 students in 7th and 8th grade were surveyed about their favorite subject. Of the students surveyed, 40 of them were 8th graders. Of the 8th graders, 11 chose math as their favorite subject, and 12 chose English. In all 20 students chose math as their favorite subject. There were 8 students in 7th grade that chose science as their favorite. Complete a two way table for this information then make a relative Frequency Table to find if the students' grade determines their favorite subject.
