Twenty individuals with chronic pain were randomly assigned to one offive doses-0.0, 0.5, 1.0, 1.5, 2.0-in milligrams (mg) of medication. The results are shown in thescatterplot below.14-12-10-2-0.00.51.01.52.0Dose (mg)The data were used to fit a least-squares regression line to predict the number of hours of pain relief for a givendose. Which of the following would be revealed by a plot of the residuals of the regression versus the dose?(A) The sum of the residuals is less than 0.(B) The sum of the residuals is greater than 0.(C) There are outliers associated with the lower doses.(D) The variation in the hours of pain relief is not the same across the doses.(E) There is a positive linear relationship between the residuals and the dose.••• •64+Pain Relief (hours)

The post-lunch dip is the drop in mental alertness after a midday meal. Does an extract of the leaves of the ginkgo tree reduce the post-lunch dip? Assign healthy people aged 18 to 40 years to take either ginkgo extract or a placebo pill. After lunch, ask them to read seven pages of random letters and place an X over every e. Count the number of misses per line read. M. K. Pawlik, "The effect of ginkgo biloba on the post-lunch dip and chemosensory function," MS thesis, Purdue University, 2002. What is a placebo and why was one group given a placebo? A placebo is a treatment pill that is presented to the individuals as a control treatment. A placebo is a lower-strength version of the pill that allows researchers to account for any physiological effect of taking the pill. O A placebo is an inert pill that allows researchers to account for any psychological effect of taking the pill. A placebo is a different pill that allows researchers to account for any variational effect of taking the…

Q5. Borer et al. [1980], study 45 individuals after an acute myocardial infarction (heart attack). They measure the ejection fraction (EF); the EF is the percent of the blood pumped from the left ventricle (the pumping chamber of the heart) during a heart beat. A low EF indicates damaged or dead heart muscle (myocardium). During follow-up four patients died. Dividing EF into low ( 35% 4. 9. 0. 32 Is there reason to suspect, at a 0.05 significance level, that death is more likely in the low EF group? Use a one-sided p-value for your answer, since biological plausibility (and prior literature) indicates low EF is a risk factor for mortality.

In a study of exhaust emissions from school buses, the pollution intake by passengers was determined for a sample of nine school buses used in the Southern California Air Basin. The pollution intake is the amount of exhaust emissions, in grams per person, that would be inhaled while traveling on the bus during its usual 18-mile trip on congested freeways from South Central LA to a magnet school in West LA. Here are the amounts for the nine buses when driven with the windows open. 1.17 0.33 0.40 0.33 1.32 0.38 0.25 0.40 0.35 (a) Consider making a stemplot. Are there outliers or strong skewness that would preclude use of the t procedures? Which is correct? A. The sample is small and the stemplot is right skewed with possible outliers, so use of t procedures is not appropriate. b. The distribution is symmetric so use of t procedures is appropriate. c. The sample is small and the stemplot is left skewed with possible outliers, so use of t procedures is…
