1. The independent variable for A, B, and C is postnatal age in hours. The dependent variables for A, B, and C are systolic blood pressure, diastolic blood pressure, and mean blood pressure respectively. The relationships between these variable is direct and positive in that as the independent variable of postnatal age increases the corresponding dependent variable increases.

2. The independent and dependent variables in Figure 3 are the same as in Figure 2, as well as the relationship between the variable. The difference is that figure 3 displays the relationship with regard to infants with a body weight of 1001-1500 grams, and figure 2 deals with infants with a body weight equal to or lesser than 1000.

3. According to figure 3,” in each instance, the y intercept was significantly greater (p < 0.001) than the value for comparable lines of best fit in infants with birth weight ≤1,000 grams.”; This is evident when comparing the y-intercepts in each graph.

4. According to the equation, the y-intercept is 43.2 and the slop is 0.17. “x” represents the independent variable of postnatal age in hours.

5. If the value of x is postnatal age of 30 hours, then the value for SBP equals 43.2 + 0.17(30) or 48.3.

6. If the value of x is postnatal age is 30 hours, then SBP = 50.3 + 0.12(30) or 53.9.

7. The SBP reading for question 6 is higher than that of question 5. This is mostly due to the significant difference in y-intercepts.

8. If the value of x is postnatal age is 30 hours, then DBP = 25.8 + 0.13(30) or 29.7.

9. If the value of x is postnatal age is 30 hours, then DBP = 30.4 + 0.11(30) or 33.7.

10. The DBP when the value of x is postnatal age of 60 hours is 30.4 + 0.11(60) or 48.3. This value is higher than the DBP when x is a postnatal age of 30 hours because the equation is the same, but the direct positive relationship correlates with a higher DBP value for a higher postnatal age.

6. What is the smallest, significant t ratio listed in Table 2? Provide a rationale for your answer.
t = 2.03* the smallest t ratio listed in Table 2. It indicates that the cholesterol level change was statistically significant from pretest to 3 months. It is greater than the given value of p<0.05

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.
The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 < 0.05 hence this suggests a rejection of the null...
