The correlation between height and weight for a certain breed of plant is found to be 0.75. What percentage of the variability i

WINSTONCH [101]

Answer:

The percentage of the variability in plant weight is NOT explained by height is

$p = 43.75$ %

Step-by-step explanation:

From the question we are told that

The correlation between height and weight is $r = 0.75$

Generally the R-Squared between height and weight is mathematically represented as

$R - square = r^2$

substituting values

$R - square = 0.75^2$

$R - square = 0.563$

This R-Squared tells us the percentage of plant weight is accounted by height

and from the calculation we see that it is 56.3%

Now the percentage of plant weight that is not accounted by height is

$p = 100 - 56.3$

$p = 43.75$ %
