A -year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Data from a portion of this study follow. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker.

A 10-year study was conducted by the American Heart Association to analyze how age, blood pressure, and smoking are related to the risk of strokes. 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. A sample data set of 18 people was used to develop an estimated regression equation to predict...

(Bonus question) Are coffee drinkers more likely to suffer from high blood pressure? For a random sample of 50 coffee drinkers, 30 had high blood pressure. In a random sample of 50 non-coffee drinkers, 25 had high blood pressure. Let p1, p2 denote the population proportion of high blood pressure among coffee drinkers and non-coffee drinkers respectively. (a) Construct a 95% CI for the difference between these two proportions p1 − p2. (3pts). (b) Someone proposes that coffee drinkers have...

A study reported in the Journal of the American Medical Association involved the study of respiratory tract infections in children aged 1 to 5 years in Israel. During the period November 1999 to March 2000 a randomly selected group of the children received a placebo and another randomly selected group received a mixture of Echinacea and Vitamin C. The following table gives the numbers for the children in each group and for those who developed pneumonia during that time. Treatment:...

A study reported in the Journal of the American Medical Association investigated the cardiac demands of heavy snow shoveling. Ten healthy men underwent exercise testing with a treadmill and a cycle ergometer modified for arm cranking. The men then cleared two tracts of heavy, wet snow (ouch!) using a lightweight plastic snow shovel and an electric snow thrower. Each subject’s heart rate was recorded under the 4 exercise modes. The Excel spreadsheet provides the heart rates for ten subjects under...

A study reported in the Journal of the American Medical Association investigated the cardiac demands of heavy snow shoveling. Ten healthy men underwent exercise testing with a treadmill and a cycle ergometer modified for arm cranking. The men then cleared two tracts of heavy, wet snow by using a lightweight plastic snow shovel and an electric snow thrower. Each subject's heart rate during snow removal were compared with the values obtained during treadmill and arm-crank ergometer testing. Dataset: HeartRate Treadmill...

Question 2: The Journal of the American Medical Association reported in 2002 on a study of 1,100 airline passengers who flew from San Francisco to Denver. 515 of these passengers traveled on planes where air was re-circulated, the remaining 585 traveled on planes that did not recirculate air. Of those that did travel on planes where the air was recirculated, 110 reported post-flight respiratory problems. Of those on planes that did not recirculate the air, 108 reported post-flight respiratory problems....
