    The correlation between height and weight for a certain breed of plant is found to be 0.75. What percentage of the variability in plant weight is not explained by height?

    1. 1−(0.75)2=0.4375 or 43.75%
    2. (1−0.75)2=0.0625 or 6.25%
    3. (0.75)2=0.5625 or 56.25%
    4. 1−0.75=0.25 or 25%
