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.

Answer:
Explanation:
Wind, solar and hydroelectric systems generate electricity with no associated air pollution emissions. Geothermal and biomass systems emit some air pollutants, through total air emissions are generally much lower than those of coal and natural gas fired power plants.
