dangina [55]

Answer:

The value of a is 150 and b is 4822.

Explanation:

First, you have to expand to remove brackets :

$(5372 + 100 {y}^{2} ) + 5(10 {y}^{2} - 110)$

$= 5372 + 100 {y}^{2} + 50 {y}^{2} - 550$

Next, you have to simplify :

$100 {y}^{2} + 50 {y}^{2} + 5372 - 550$

$= 150 {y}^{2} + 4822$

Next, you have to compare it :

$a {y}^{2} + b = 150 {y}^{2} + 4822$

$a = 150$

$b = 4822$

Suppose the correlation between two variables x and y is. 8. That means the correlation between y and x is -. 8.

The given statement about the correlation between two variables is; False

<h3>Pearson's correlation coefficient </h3>

Pearson's correlation coefficient is the measure of linear correlation between two sets of data.

Pearson's r is always between the values of -1 and +1.

In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.

Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.

Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.
