    In a random sample, the variables X and Y were measured in eight individuals were measured. The Spearman rank correlation coefficient rS of X and Y is -0.69. If we use the Pearson correlation coefficient to prove this null hypothesis that the true correlation in the population is 0 would want to test (5% risk, two-sided) then the limits of the critical range are


    1. FALSE: +/- 0.6319
    2. FALSE: +/- 0.7067
    3. TRUE: +/- 0.6664
    4. FALSE: +/- 0.7646

    1. +/- 0.6319: Incorrect
    2. 0.7067: Incorrect
    3. +/- 0.6664: Correct
