5. Using the values a = 7.241 and b = 0.176 with the novel formula in Figure 2, what is the predicted weight in kilograms for a child 3 years of age? Show your calculations.
6. Using the values a = 7.241 and b = 0.176 with the novel formula in Figure 2 , what is the predicted weight in kilograms for a child 5 years of age? Show your calculations.
7. In Figure 3, some of the actual mean weights represented by blue line with squares are above the dotted straight line for the novel formula, but others are below the straight line. Is this an expected finding? Provide a rationale for your answer.
8. In Figure 3, the novel formula is (weight in kilograms = (0.331 × Age in months) − 6.868. What is the predicted weight in kilograms for a child 10 years old? Show your calculations.
9. Was the sample size of this study adequate for conducting simple linear regression?
