Question

A two-way frequency table shows grades for students in college and students in high school:

High schoolCollegeTotal
GPA above 3.0 14 26 40
GPA below 3.0 46 14 60
60 40 100


Based on this data, are "being in high school" and "GPA above 3.0" independent events?
Yes, P(high school | GPA above 3.0) = P(high school)

Yes, P(high school | GPA above 3.0) = P(GPA above 3.0)

No, P(high school | GPA above 3.0) ≠ P(high school)

No, P(high school | GPA above 3.0) ≠ P(GPA above 3.0)
