1. According to the study narrative and Figure 1 in the Flannigan et al. (2014) study, does the APLS UK formulae under- or overestimate the weight of children younger than 1 year of age? Provide a rationale for your answer. The APLS UK formula overestimates the weight 10-25.4% as they are using the APLS revised formula, and alpha of 0.05 multiplied by age in months and adding 4 inches. 2. Using the values a = 3.161 and b = 0.502 with the novel formula in Figure 1, what is the predicted weight in kilograms (kg) for a child at 9 months of age? Show your calculations. y=0.502 (9) + 3.161 y= 4.518 + 3.161 y= 7.679 kg at 9 mths of age 3. Using the values a = 3.161 and b = 0.502 with the novel formula in Figure 1, what is the predicted weight in kilograms for a child at 2 months of age? Show your calculations. y=0.502 (2) +3.161 y= 1.004 + 3.161 y= 4.165 kg at 2 mths of age 4. In Figure 2, the formula for calculating y (weight in kg) is Weight in kg = (0.176 × age in months) + 7.241. Identify the y intercept and the slope in this formula. y intercept is 7.241, slope is 0.176. (y intercept = weight in kg, slope is 0.176 x age in months) 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. y (wt in kg) = (0.176 x (3x12) + 7.241 y=(0.176 x 60) + 7.241 y= 10.56 + 7.241 y= 17.801 kg at 60 mths or 5 yrs of age
