0.276×100=27.6%
Answer:
Options a, b, c are correct.
Step-by-step explanation:
First let's see the equation that governs the statement, which is the following:
![r = \frac{cov (x, y)}{\sqrt{var(x) var (y)} }](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Bcov%20%28x%2C%20y%29%7D%7B%5Csqrt%7Bvar%28x%29%20var%20%28y%29%7D%20%7D)
Therefore, reading options a, b, c are correct.
Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.
This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.
that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
