A Multiple Regression Analysis Was Used to Test the Values

question 11

Multiple Choice

A multiple regression analysis was used to test the values of visual acuity, swing power, and cost of clubs for predicting golf scores. The regression analysis showed that visual acuity and swing power predicted significant amounts of the variability in golf scores, but cost of clubs did not. What can be concluded from these results?

• A) Cost of clubs and golf scores are not correlated.
• B) Cost of clubs adds predictive value above and beyond the predictive value of visual acuity and swing power.
• C) The regression coefficient of cost of clubs is equal to zero.
• D) Removing cost of clubs from the overall model will not reduce the model's R² value significantly.
