Answer:
The correlation between height and weight for a certain breed of plant is found to be 0.75. the percentage of the variability in plant weight is not explained by height is 43.75%
Step-by-step explanation:
Given:
The correlation between height and weight of certain plant = 0.75
To find:
Percentage of plant that cannot be calculated by height = ?
Solution:
The
between the variables
The

= 0.5625
which is 56.25% of variability in the plant weight calculated on the basis of height.
Hence, the variability which has not been explained by the model is,
= 1-0.5625
= 0.4375
= 43.75%
Percentage of plant that cannot be calculated by height is 43.75%
