One such study relates happiness with age and finds that holding everything else constant, people are least happy when they are in their mid-40s (The Economist, December 16, 2010). The accompanying table shows a portion of data on a respondent's age and his/her perception of well-being on a scale from 0 to 100.

(Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.) Sample correlation coefficient a-2. Interpret the sample correlation coefficient between age and happiness. The correlation coefficient indicates a positive linear relationship. The correlation coefficient indicates a negative linear relationship. The correlation coefficient indicates no linear relationship. b-1. Specify the competing hypotheses in order to determine whether the population correlation between the age and happiness differs from zero.
