   Question

   In a study of a possible relationship between concentration and school performance, the rank correlation coefficient rS = .45 is calculated for a randomly selected group of 20 students.

   Using an rS test, we must accept the hypothesis that the variables correlate at:

   
   
   1. FALSE: $\alpha$ = 1% and $\alpha$ = 5%
   2. FALSE: $\alpha$ = 1% and niet bij $\alpha$ = 5%
   3. TRUE: $\alpha$ = 5% and not at $\alpha$ = 1%*
   4. FALSE: Nor at $\alpha$ = 5%, nor at $\alpha$ = 1%
