1. When studying the relationship between ankle-brachial blood pressure index and peripheral vascular disease the researchers have a significant R square. They then add a second independent variable of a pain scale. The R square in the model that includes both independent variables is significant but the R square change is not. You know this means:
A. The second variable added may not be significant and should be examined further
B. Having both variables in the model explains significantly more variation in peripheral vascular disease
C. The R square change only matters with the first variable
D. Because the model is significant both variables should be included

1. (55 points) The investigators are interested in asses the relationship between Systolic Blood Pressure (SBP) in mm Hg and Age in years among Hypertensive Patients. Specif- ically, whether a patient's SBP can be predicted from his or her age. They selected n=122 patients at random from a medical record database in a hospital. Assume that the simple linear regression model is appropriate. The following table shows regression output of a simple linear regression model relating the SBP to the...
unk food (e g. potato chips) are typically packaged to appeal to children. Can similar packaging of a healthy food product Rerase children's desire to consume the product? The Journal of Consumer Behavior (2011) explored this topic rs randomly selected a sample of 100 school children. Each child was given an apple in the cartoon packaging to rate their willingness to eat the apple. Later, on another day, the children were given carrots with the same type ing with the...
Problem 1 Cheetah Delivery operates a fleet of local delivery vehicles. Management wants to estimate the fixed and variable costs per mile. Industry standards indicate variable costs should be no more than $.29 per mile. Cheetah collected the following data for the delivery service for last month to test against the industry standard: Truck Number Costs Miles 1 $370 1280 2 360 1220 3 340 1100 4 400 1190 5 370 1190 6 420 1330 7 330 1000 8 310...
The following ANOVA model is for a multiple regression model with two independent variables: Degrees of Sum of Mean Source Freedom Squares Squares F Regression 2 60 Error 18 120 Total 20 180 Determine the Regression Mean Square (MSR): Determine the Mean Square Error (MSE): Compute the overall Fstat test statistic. Is the Fstat significant at the 0.05 level? A linear regression was run on auto sales relative to consumer income. The Regression Sum of Squares (SSR) was 360 and...

explaim the mechanisms amd toxological effects if type 1 diabetes in this article Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...
