Find a 95% confidence interval for problem #3 and B. Determine if agrees with the hypothesis conclusion or not.
Does aspirin reduce heart attacks? In a study 11037 male physicians were given aspirin daily and 139 experience a heart attack within a 10-year period, while 11034 male physicians were given a placebo daily and 239 experienced a heart attack in the same 10-year period. Use a significance level of .05 to test the claim that daily use of aspirin reduces the proportion of those who get heart attacks.

A study occurred to test whether taking aspirin can reduce the chance of having a heart attack. Over 20000 male medical doctors aged 40 through 84 were given a 325 mg tablet every other day. Just over half of the doctors (11037) were given aspirin tablets; the rest (11034) were given placebos. There were 104 heart attacks in the aspirin group and 189 in the placebo group. Analyze!!!! (By which I mean perform a relevant hypothesis test and/or construct an...

In a trial designed to test the effectiveness of aspirin in preventing heart disease, 11,037 male physicians were treated with aspirin and 11,034 male physicians were given placebos. Among the subjects in the aspirin treatment group, 139 experienced myocardial infarctions (heart attacks). Among the subjects given placebos, 239 experienced myocardial infarctions (based on data from “Final Report on the Aspirin Component of the...

mapep reventing heart attacks: Medical researchers performed a comparison of two drugs, clopidogrel and ticagrelor, which are esigned to reduce the risk of heart attack or stroke in coronary patients. A total of 6740 patients were given clopidogrel, and 662 were given ticagrelor. Of the clopidogrel patients, 571 suffered a heart attack or stroke within one year, and of...

1. In the regression equation, the value that gives the amount by which Y changes for one unit in X is called the (a) coefficient of correlation. (b) coefficient of determination. (c) slope. (d) intercept. 2. For any two categorical variables, X and Y, the best way to determine if they are related is to (a) calculate the correlation between X and Y. (b) draw a scatterplot of the X and Y values. (c) make a two-way table of the...
