Exercise 27 5. In the legend beneath Figure 2[->0]‚ the authors give an equation indicating that systolic blood pressure 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 ≤1‚000 grams? Show your calculations. Y = a + bx 43.2 + 0.17(30) = 48.3 The SBP for neonates ≤1‚000 grams at 30 hours is 48.3. 6. In the legend beneath Figure 2[->1]‚ the authors give an equation indicating that systolic blood pressure is SBP = 50.3 + 0.12x

Exercise 36 Answers 1. Since the F value is significant‚ based on the p-value of 0.005 which is less than 0.05 which is sufficient to reject the null hypothesis. This suggests that there is a difference in the control and treatment groups. 2. Since the p- value is less than 0.05 and therefor the null hypothesis can be rejected. This presents that the mean‚ difficulty and mobility scores‚ must be different 3. The result was statistically significant with a probability score of p < 0.001.
