Statistics

Suppose a linear regression equation was calculated to fit the relationship between the percentage of the adult population that is obese and the percentage who felt that they are very happy. These variables were measured on the population level of each of the United States and territories. How would you interpret the following estimated regression equation? Very happy (%) = 70.3 - 2.58 x Obese (%) Select one:

a. Slightly over 70% of the variation in the percent who are very happy is explained by obesity.

b. The variation in percent that are very happy that are explained by the model is 2.58.
