If the correlation coefficient between two variables is .90, what percent of the variance is explained by this correlation
1 answer:
Answer: 81% of the variance in dependent variable is explained by this correlation .
Step-by-step explanation:
For X = Independent variable and Y=dependent variable,
If r= correlation coefficient , then we say <em> </em>of the<em> </em>variance in Y is explained by Variable X.
Given: r= 0.90
So, 81% of the variance in dependent variable is explained by this correlation .

Answer:
a, the first option
Step-by-step explanation:
You solve the inequality equation just like any other equations. The only difference is that you gotta flip the sign whenever you multiply or divide by a negative number.
The result is p>32, which is an open-circle at 32 that points toward all values greater than 32
