Please answer all the details of the question

We are modeling weight (outcome, in pounds), based on age (in years), height (in inches), and cholesterol (in their units of mg/dL). The results are below. From the first table: (1 point) (a) Fill in the missing values of the ANOVA table (there are 4 items that need to be filled in) (2 points) (b) Is the model significant with alpha at 0.05? From the second table: (1 point) (c) Write the model that was fit (2 points) (d) Interpret the coefficient for 'age' and whether it is statistically significant at the 5% alpha level Table 1: Sum of Mean Source DF Squares Square F Value Regression ? ? ? ? 18951 6316.95514 ??? ?
