Circle the correct response: y is used as the predicted value when the linear correlation coefficient p is EQUAL/NOT EQUAL to zero.
Homework Answers
Answer: y is used as the predicted value when the linear correlation coefficient p is NOT EQUAL to zero.
Explanation:
We know that when we reject the null hypothesis that linear correlation coefficient p = 0, then we conclude that there is statistically significant relationship exists between the given variables. That is, the value of the linear correlation coefficient is different than zero. If the value of linear correlation coefficient is zero, then there is no any correlation or relationship exists between given variables. This means, we can use the regression equation for the prediction of dependent variable y, if the linear correlation coefficient p is NOT EQUAL to zero.
