Suppose the correlation between two variables x and y is. 8. That means the correlation between y and x is -. 8.
den301095 [7]

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.

Replacement  reaction  is  a   type  of  chemical reaction in  which   an  element  react  with  a  compound  and  take the  place  of another  element  in that compound.

Zn  is  more reactive than  Cu, therefore Zn replaces   cu from   CU(NO3)2  to form  Zn(NO3)2  +Cu
