A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Assume the following data are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will have a stroke over the next 10-year period. For the smoking variable, define a dummy variable with 1 indicating a smoker and 0 indicating a nonsmoker. (See the Stroke file in the document...

You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients. You do some...
The accompanying computer excel output (please see attachment on Blackboard) provides details of data and analysis on the topic of “patient satisfaction”. A hospital administrator wished to study the relation between patient satisfaction (Y) and patients’ age (X1, in years) , severity of illness (X2), and anxiety level (X3). The output includes a listing of all 46 observations; descriptive statistics for each variable; and, the results of a regression analysis that uses patient satisfaction as the dependent variable, and patient’s...
A recent 10-year study conducted by a research team at the Great Falls Medical School was conducted to assess how age, systolic blood pressure, and smoking relate to the risk of strokes. Assume that the following data are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will have a stroke over the next 10-year period. For the smoking variable, define a dummy variable with 1 indicating a smoker and 0 indicating...

Student stress at final exam time comes partly from the uncertainty of grades and the consequences of those grades. Can knowledge of a midterm grade be used to predict a final exam grade? A random sample of 200 BCOM students from recent years was taken and their percentage grades on assignments, midterm exam, and final exam were recorded. Let’s examine the ability of midterm and assignment grades to predict final exam grades. The data are shown here: Assignment Midterm FinalExam...
