An article presents the results of a study of soft drink and smoking habits in a sample of adults. Of 11705 people who said they consume soft drinks weekly, 2527 said they were smokers. Of 14685 who said they almost never consume soft drinks, 2503 were smokers. Find a 95% confidence interval for the difference between the proportions of smokers in the two groups. (Round the final answers to four decimal places.)

A soft drink manufacturer wishes to know how many soft drinks adults drink each week. They want to construct a 95% confidence interval with an error of no more than 0.08. A consultant has informed them that a previous study found the mean to be 3.1 soft drinks per week and found the variance to be 0.49. What is the minimum sample size required to create the specified confidence interval? Round your answer up to the next integer.

A medical researcher conjectures that smoking can result in the wrinkled skin around the eyes. The researcher recruited 150 smokers and 250 nonsmokers to take part in an observational study and found that 95 of the smokers and 105 of the nonsmokers were seen to have prominent wrinkles around the eyes (based on a standardized wrinkle score administered by a person who did not know if the subject smoked or not). How do the smokers compare to the non-smokers? Find...

In one study of smokers who tried to quit smoking with nicotine patch therapy, 39 were smoking one year after the treatment, and 32 were not smoking one year after the treatment (based on data from "High-Dose Nicotine Patch Theory," by Dale et al., Journal of the American Medical Association, Vol. 274, No.17). Provide a 99% confidence interval for the proportion of smokers who are smoking again one year after their treatment.

Medical researchers are concerned about the association between maternal smoking habits and the need for caesarian section during birth. Suppose the researchers gather 423 expecting mothers in their third trimester and follow them through pregnancy to examine the incidence of caesarian. Suppose out of the 102 mothers that reported smoking cigarettes at least once during pregnancy, 59 of them were referenced to have needed caesarian intervention during delivery, while 73 of the mothers with no smoking history reportedly needed the...

5. In a random sample of 500 people in their 30's, 22% were smokers. In a random sample of 450 people in their 20's, 14% were smokers. The 95% confidence interval for the difference between the population proportions P20's - P30's. turned out to be: -0.128 < p1 - p2 < -0.032. What does this imply? There is not a significant difference between the smoking habits of people in their 20's and people in their 30's, but the sample showed...
