In a nationwide study directed by Detroit’s Henry Ford Hospital, 780 persons with stableheart disease were treated. Half of the subjects were treated with drugs and half underwentbypass surgery. After 6 years, 351 of those treated with drugs and 359 of those who underwentbypass surgery were still alive. Use a level 0.01 test to determine if there is sufficient evidenceto indicate that surgery is a more effective treatment.

Do sports drinks help prevent cramps in endurance sports? At the end of a marathon, officials will ask runners if they drank water or a sports drink during the race, along with whether or not they suffered any cramps. Is this an observational study or experiment?
Urban legend says that knuckle cracking is bad for you and will eventually lead to osteoarthritis of the hand joints. A retrospective case-control study of individuals who had received an X-ray of the right hand in the past 5 years enrolled 180 subjects with a confirmed diagnosis of hand osteoarthritis and 95 control subjects in the same age group. The study found that 36 subjects with hand osteoarthritis and 25 control subjects were habitual knuckle crackers. Is there good evidence that the proportion of knuckle crackers is greater among individuals with hand osteoarthritis? Does this support the urban legend about knuckle cracking?
At one hospital in 1992, 674 women were diagnosed with breast cancer. Five years later, 88% of the Caucasian women and 83% of the African American women were still alive. Identify the study as an observational study or a designed experiment.
In a recent study; it was found that 62 percent of college students drink heavily and drive. Assuming all conditions are met, a police chief wanting to enact an emergency protocol for DWI/DUI wants to know if the claim is accurate. He took a sample of 70 college students who drank and drove and found that 46 of those students had a high blood alcohol level. Can we claim that more than 62 percent of all college students drink heavily and drive?
A new drug to treat psoriasis has been developed and is in clinical testing. Assume that those individuals given the drug are examined before receiving the treatment and then again after receiving the treatment to determine if there was a change in their symptom status. If the initial results showed that 3.0% of individuals entered the study in remission, 74.0% of individuals entered the study with mild symptoms, 13.0% of individuals entered the study with moderate symptoms, and 4.0% entered the study with severe symptoms calculate and interpret a chi-squared test to determine if the drug was effective treating psoriasis given the information below from the final examination. Remission (No Symptoms of Psoriasis) Mild Symptoms of Psoriasis Moderate Symptoms of Psoriasis Severe Symptoms of Psoriasis Total Number of Participants to Receive the Drug Number of Participants 455 635 85 7 1182
A scientist is studying the effect of a new type of exercise program on cardiovascular health. The scientist randomly assigns individuals to either the exercise program or a control group. The scientist wants to determine if the exercise program has a statistically significant effect on cardiovascular health. The scientist monitors cardiovascular health by measuring the blood pressure of each individual.

In an article about unusual allergies, a doctor explained that allergy to sulfites is usually seen in patients with asthma. The typical reaction is a sudden increase in asthma symptoms after eating a food containing sulfites. Studies are performed to estimate the percentage of the nation's 10 million asthmatics who are allergic to sulfites. In one survey, 39 of 600 randomly selected asthmatics in the country were found to be allergic to sulfites. Find and interpret a 95% confidence interval for the proportion, p, of all asthmatics in the country who are allergic to sulfites.
