We will write a custom paper specifically for you.
- What are the independent and dependent variables in Figures 3, A, B, and C? How would you describe the relationship between the variables in Figures 3, A, B, and C?
- Was there a significant difference in the y intercept for the lines of best fi t in Figure 2 from the y intercept for the lines of best fi t in Figure 3? Provide a rationale for your answer.
- Ŷ represents the predicted value of y calculated using the equation Ŷ Figure 2, the formula for SBP is Ŷ=43.2+0.17x. Identify the y intercept and the slope in this formula. What does x represent in this formula?
5.In the legend beneath Figure 2, the authors give an equation indicating that systolic bloodpressure is SBP = 43.2 + 0.17x. If the value of x is postnatal age of 30 hours, what is the value for Ŷ or SBP for neonates d1,000 grams? Show your calculations. In the legend beneath Figure 2, the authors give an equation indicating that systolic blood pressure is SBP = 50.3 +0.12x. If the value of x is postnatal age of 30 hours, what is the value for Ŷ or SBP for neonates 1,001–1,500 grams? Show your calculations.
- Using the values a = 500 and b = 20 in Figure 27-2, what is the predicted birth weight in grams for an infant at 36 weeks of gestation?
- Compare the SBP readings you found in Questions 5 and 6. Explain the difference in these two readings.
- In the legend beneath Figure 2, the authors give an equation indicating that diastolic bloodpressure is DBP = 25.8 + 0.13x. If the value of x is postnatal age of 30 hours, what is the value for Ŷ for neonates d 1,000 grams? Show your calculations.
- In the legend beneath Figure 3, the authors give an equation indicating that diastolic bloodpressure is DBP = 30.4 + 0.11x. If the value of x is postnatal age of 30 hours, what is the value for Ŷ for neonates 1,001–1,500 grams? Show your calculations.
- In the legend beneath Figure 3, the authors give an equation indicating that diastolic bloodpressure is DBP = 30.4 + 0.11x. How different is the DBP when the value of x is postnatal age of 60 hours versus the 30 hours examined in Question 9?
