true false 1-3 i feel it would be false because i thought you can not decide causation, is this always the case
1-4 i think it would be true, but i do not really understand the statement

Comments:

  Rebecca G.  says:
1-3 is false for the reason you state.

1-4 is true as changing the unit does Not change the correlation coefficient

For example, if you had X's and Y's representing dollars and you converted the X's and Y's to cents, the correlation would remain the same.
