Which question is statistical?

It’s the last one

The first one is just converting measures, the middle 2 are asking for a specific piece of information and not a set of data,

The last one is statistical because it requires/is a data set and it is graph-able

C, as they are on the same plane, (it is uncommon to find non co-planar lines)
D, as that symbol means parallel

A is untrue as they are on the same plane
B is untrue as that symbol means perpendicular
E is untrue as perpendicular means the two lines intersect and form 90 degree angles
F is untrue as parallel lines never intersect
