27. Lower Limb Surgery. The study "Intrathecal Sufentanil ver-sus Fentanyl for Lower Limb Surgeries- A Randomized ControlledTrial" (Journal of Anaesthesiology Clinical Pharmacology, Vol. 27,Issue 1, pp. 67-73) by P. Motiani et al. compares two different agents,intrathecal sufentail and fentanyl, used in enhancing the anesthesiol-ogy of patients receiving major lower limb surgery. One variable com-pared between the two agents was the amount of blood loss during thesurgery. Based on the study, we will assume that, using fentanyl, theamount of blood loss during major lower limb surgery is normallydistributed with mean 283.3 ml and standard deviation 83.3 ml. Findthe percentage of patients whose amount of blood loss during majorlower limb surgery using fentanyl isa. less than 304 ml.b. between 221 and 429 ml.c. more than 450 ml.

We have given that the random variable X i.e, the amount of blood loss during major lower limb…

Trans-Generational Effects of Diet Can experiences of parents affect future children? New studies16 suggest that they can: Early life experiences of parents appear to cause permanent changes in sperm and eggs. In one study, some male rats were fed a high-fat diet with 43% of calories from fat (a typical American diet), while others were fed a normal healthy rat diet. Not surprisingly, the rats fed the high-fat diet were far more likely than the normal-diet rats to develop metabolic syndrome (characterized by such things as excess weight, excess fat, insulin resistance, and glucose intolerance.) What surprised the scientists was that the daughters of these rats were also far more likely to develop metabolic syndrome than the daughters of rats fed healthy diets. None of the daughters and none of the mothers ate a high-fat diet and the fathers did not have any contact with the daughters. The high-fat diet of the fathers appeared to cause negative effects for their daughters. What are the…
A study is planned to investigate risk factors for sudden cardiac death. A cohort of men and women between the ages of 35 and 70 is enrolled and followed for up to 20 years. As part of the study, participants provide data on demographic and behavioral characteristics; they also undergo testing for cardiac function and provide blood samples to assess lipid profiles and other biomarkers. A new measure of inflammation is hypothesized to be related to sudden cardiac death. Describe its strengths and weaknesses.
sto ave 12.72 (M4) The authors of the paper "Serum Zinc Levels of Cord Blood: Relation to Birth Weight and Gestational Period" (Journal of Trace Elements in Medicine and Biology [2015]: 180-183) car- ried out a study of zinc levels of low-birth-weight babies and normal-birth-weight babies. For a sample of 50 low- birth-weight babies, the sample mean zinc level was 17.00 and the standard error was 0.43. For a sample of 73 normal-birth-weight babies, the sample mean zinc level was 18.16 and the standard error was 0.32. Explain why the two standard errors are not the same.
A study was made of 413 children who were hospitalized as a result of motor vehicle crashes. Among 290 children who were not using seat belts, 60 were injured severely. Among 123 children using seat belts, 16 were injured severely (based on data from "Morbidity Among Pediatric Motor Vehicle Crash Victims: The Effectiveness of Seat Belts," by Osberg and Di Scala, American Journal of Public Health, Vol. 82, No. 3). For this problem we want to know, is there sufficient sample evidence to conclude, at the 0.05 significance level, that the proportion of severe injuries is higher for children not wearing seat belts? Let pi be the proportion of severe injuries among all children not wearing seatbelts and who were involved in crashes. Let p2 be the proportion of severe injuries among all children wearing seatbelts and who were involved in crashes. Which is the proper expression of Ho?

A randomized controlled trial was conducted to determine whether treatment with daily aspirin was more effective than placebo at preventing myocardial infarction (MI) (within 5 years). A total of 140 out of 11,140 subjects in the aspirin group experienced an MI, while 240 out of 11,040 subjects in the placebo group experienced an MI. The relative risk of MI comparing aspirin to placebo was calculated to be 0.58, and its 95% confidence interval ranged from 0.47 to 0.71. Which of the following can be concluded from these results? Question 4 options: On average, the risk of MI among subjects who used aspirin was 0.58 times the risk of MI among those on placebo. On average, aspirin reduced the risk of MI in this population by 58% when compared to placebo. Aspirin is almost certainly harmful to this population. Compared to placebo, aspirin did not reduce the risk of MI by a statistically significant amount.

What are the df values for the F-ratio evaluating the interaction?
