Question 3. A city is studying the role of drug use on vehicle accidents. The officials obtainexperimental research results that suggests that driving under the influence (DUI) culminates inaccidents more frequently than driving sober (~DUI)P(Accident|DUI) = 0.4 whereas P(Accident|~DUI) = 0.1Suppose that anonymous survey research suggests how prevalent driving under the influence isin the city, P(DUI) = 0.25.i)ii)iii)Show that Accident and DUI are not statistically independent variables.Find how likely it is that an accident in this city involved a driver who was under theinfluence, P(DUI|Accident).For the two conditional probabilities, P (Accident | DUI) and P(DUI Accident),explain which relationship between the events is a causal one, and which is aninferential one.

Data was collected from 60 students from the SAT, the average sat score was 909 with a standard deviation of 178. The average ACT score was 19 with a standard deviation of 3.5. The correlation between the two variables is 0.811. a) To predict the SAT score from the ACT score, what is the equation of the leasts-square regression line. b) What fraction of the variation in the values of the SAT scores is accounted for by the linear relationship between SAT and ACT scores. Explain
In a recent study, investigators were interested in examining the association between blood glucose concentration at hospital admission and mortality in the hospital among patients with Sepsis in 3 Ugandan hospitals. Patients were followed from admission to the hospital until the end of the study. The study population included 418 admitted adult patients. Among the 280 patients with hyperglycemia (defined as a glucose concentration of >6.1 mmol/L), 80 died within the hospital from severe sepsis. Among the 138 patients with hypoglycemia (defined as a glucose concentration of <4.4 mmol/L), 30 died within the hospital from severe sepsis. Assume there is minimal loss to follow-up and no competing risks. What study design is described above? Prospective open cohort study Prospective closed cohort study Retrospective open cohort study Retrospective closed cohort study Case control study
A method of estimating earth temperature based on local precipitation is to build models based on 100s of years of earth at several different constant green house gas level (So constant global temperature for 100s of years) , and compare the correlation of statistical relationships between predicted precipitation patterns in a region, and observed precipitation patterns for a region in a few year time period.
QUESTION 22 "A psychotherapist investigating whether clients revealed more information while sitting in an easy chair or when lying down on a couh, so she randomly assignd 15 clients to each condition. The third session for each client was videotaped, and an independent observer counted the client?s disclosures and the two groups were then compared. They find that clients who sit reveal an average of 3.04 disclosures, variance = 8.92. While the clients who lay down share an average of 4.46 disclosures, with a sample variance = 9.05. psychotherapist would observe given this data? (Be sure to round your response a sample would be the test statistic the with What to the second decimal place). "
