DESIGN AND ANALYSIS OF EXPERIMENTSq3 A chemical production process consists of the first reaction with an alcohol and secondreaction with the base. A 3X2 factorial experiment with three alcohols and two baseswas conducted with unequal replications among the six treatment combinations of thetwo factors. The data are given below:Base12190.7; 91.487.3; 83.8;91.5Analyse the data and draw conclusions.Alcohol289.3; 88.1;90.494.7398.5; 86.7;88.3; 90.391.3; 90.7;91.5

Question Red Wine and Weight LossResveratrol, a compound in grapes and red wine, has been shown to promote weight loss in rodents and now in a primate.1 Lemurs fed a resveratrol supplement for four weeks had decreased food intake, increased metabolic rate, and a reduction in seasonal body-mass gain compared to a control group. Suppose a hypothetical study is done for a different primate species, with one group given a resveratrol supplement and the other group given a placebo. We wish to see if there is evidence that resveratrol increases the mean metabolism rate for this species. (This exercise presents hypothetical data. We will see the results from the actual study later in this chapter.) (a) State the null and alternative hypotheses.Let group 1 be the species taking a resveratrol supplement and let group 2 be the species taking a placebo.
21. Causation Imagine that a team of researchers collects basic information from every student in a large high school (N=1000) and monitors the students' academic performance over a single school year. The researchers find that the students who wear glasses had significantly better grades than the students without glasses. What can we reasonably conclude from this study? Pick ONE option Wearing glasses causes students to achieve better grades The results do indicate some type of causal relationship, but we should be careful generalizing from this one high school -- the effect might not exist in the broader student population. Even if the high school was representative of the broader student population, the results do not indicate any causal link between glasses and academic performance. None of these statements offer reasonable conclusions.
a) What is the strongest independent variable for the model predicting self-control for respondents living in good neighborhoods? and living in bad neighborhoods? b) In every situation above, the standard errors for the model predicting self-control for respondents in good neighborhoods are lower than the standard errors predicting self-control for respondents in bad neighborhoods. What might be one reason why this might occur?
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…
