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.…
4. Compare the mean baseline and posttest depression scores of control group. Do these scores strengthen or weaken the validity of the research results? Provide a rationale for your answer.…
In this activity you will collect data and then perform statistical analyses to determine measures of central tendency and variation of the data. You will also represent the data using a histogram.…
7. Assuming that the distribution of scores for the postoperative CVLT Retrieval T scores is normal, the middle 68% of the patients had T scores between what two values?…

3. Compare the mean baseline and posttest depression scores of the experimental group. Was this an expected Finding? Provide a rationale for your answer. The Experimental group’s mean depression baseline score(mean-14.00) was 0.64 points higher than its posttest mean score ( mean-13.36) because on the average the experimental group subjects scored higher on the baseline than after the end of the empowerment program. This was an expected finding because it was hypothesized that after the completion program, the experimental group’s depression will be lowered and they will be empowered to increase their self-efficacy skills. This finding indicates that the empowerment intervention helped to lower depression on ESRD patients.…
4) No, the distributions of scores were not similar for the two groups. Experimental group has slightly higher dispersion (n=30 and SD= 7.78) than control group (N=33 and SD=7.2). Standard deviation decreases with larger sample sizes.…
5. Compare the 3 months and 6 months t ratios for the variable Exercise from Table 3. What is your conclusion about the long-term effect of the health-promotion intervention on Exercise in this study?…
The sample size table suggests that 2 deviations are acceptable for the second control, had Darrell tested 77 samples. However, his sample size consisted of only 58 items, so the 2 deviations found are not acceptable unless further testing is conducted. The evaluation table also indicates that the computed upper deviation rate is approximately 11%, which is higher than the acceptable deviation rate for the control. More evidence must be gathered before it can be concluded that the control is reliable.…
