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

The T score was 50. 10x47.8/5.8+(50-10x47.8/5.8) 10x47.8=478 478/5.8=82.41 50-82.41= -32.41 -32.41+82.41=50 2. Which patient scored the lowest on postoperative CVLT Retrieval? What was this patient’s T score? Pt. 4 had a post-op CVLT retrieval score of 23. 10*47.8/5.8+(23-10*47.8/5.8 10x47.8=478

EXERCISE 36 Questions to be Graded 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F (1‚ 22) = 9.619‚ p = 0.005. Discuss each aspect of these results. Answer: The F value suggests there is a significant difference between the results of the control and treatment groups. The P-value of 0.005 is < the alpha of 0.05.This suggest that the groups are significantly

Questions to be Graded 1. Were the groups in this study independent or dependent? Provide a rationale for your answer. They were independent. There was a two-factor analysis that was used and the data was collected independently. 2. t –3.15 describes the difference between women and men for what variable in this study? Is this value significant? Provide a rationale for your answer. Mental Health Yes the value of 0.02 is significant because it is less than the number that was selected

The purpose of the graded exercise test is to assess the cardiorespiratory capacity (VO2 max). The VO2 max is used to identify the level of cardiorespiratory fitness of the individual. Days before the graded exercise test‚ I’ll give Tonya instructions‚ such as eating breakfast‚ but no tea‚ coffee‚ and chocolate because caffeine may affect performance and results.
