Question
9 Marks: 1 Using the same population two researchers wantto estimate the relationship between happiness and wealth.Happiness is measured on a scale of one to ten. Wealth is measuredby annual income in dollars.Research A reports the following:
r = 0.110, P = 0.000
Researcher B reports the following:
r = 0.117 , P = 0.237
What is the best answer? Choose one answer. A. Researcher Ashould conclude that annual income is a statistically andpractically significant predictor of happiness. B. Both researchersshould conclude that annual income has no practical value inpredicting the level of people's happiness. C. Based on the Pvalues, researcher A should use annual income to predict happinessand researcher B should not. D. Given that bothresearchers found almost the same value for r but different Pvalues, one of them must have made a calculationerror.
