He ran a multiple linear regression, which included four predictors ('hours spent taking part in physical activity per day', 'calories consumed per day', 'BMI', and 'hours spent watching TV per day') . His model had a R² of .665, an adjusted R² of .661, an F-statistic of 112.56 (p 0.00) . How would you interpret his findings

• A)It is not a significant model.
• B)It is a significant model where the four predictors account for 66% of the variance in the children's scores in the fitness test.
• C)It is a significant model where the four predictors account for 112% of the variance in the children's scores in the fitness test.
• D)It is an significant model where the four predictors account for 0.661 of the variance in the children's scores in the fitness test..
