If two variables are highly correlated, it not only means that they are linearly related, it also means that a change in one variable will cause a change in the other variable.

Solution

True.

Correlation gives the measure of linear relation between two variables. If two variables X and Y are correlated, then the relation between them can be written as -

Y = a + bX.

So, if we change any one of the two variables, this would change the other variable too.
