Arecent study investigated the extent to which hypertension is affected by alcohol consumption. among other things, the study compared the rate of hypertension in nondrinkers to the rate in people that are moderate beer drinkers (average between 0.5 and 1 glass of beer per day). they found that a 95% confidence interval for the relative risk of hypertension in moderate beer drinkers as compared to nondrinkers was 0.47 to 0.90. a relative risk of 1 means that the two groups have the same risk of hypertension, while a relative risk of less than 1 means that moderate beer drinkers have less risk of hypertension than nondrinkers. if the researchers who ran the study had tested the hypotheses h0: the relative risk for moderate beer drinkers as compared to nondrinkers = 1 ha: the relative risk for moderate beer drinkers as compared to nondrinkers ≠ 1 they would have concluded which of the following? a) reject h0 b) fail to reject h0 at level 0.10 c) neither choice is correct. we cannot determine what we would do at level a = 0.10 because the interval given is a 95% confidence interval, not a 90% confidence interval.

For many years, states levy a special sales tax on wine often called a "sin tax". the reasoning behind these special sales taxes is that wine consumption can lead to particular social costs such as drunk driving, violence, etc. however, many medical studies have demonstrated that moderate consumption of red wine can lower the risks for many diseases such as coronary heart disease. thus, there are social benefits as well. suppose that states, in recognition of some of the benefits to wine consumption, decide to decrease the sales tax on oregon pinot noir. what effect will this have on consumer surplus, producer surplus, and deadweight loss. consumer surplus increases, producer surplus increases, and deadweight loss decreases. consumer surplus decreases, producer surplus increases, and deadweight loss is unchanged. consumer surplus increases, producer surplus increases, and deadweight loss increases. consumer surplus decreases, producer surplus decreases, and deadweight loss decreases.

Adiet high in saturated fats increases a person's risk of developing heart disease. regular consumption of red wine reduces that risk. per-capita consumption of saturated fats is currently about the same in france as in the united states, but there is less heart disease there than in the united states because consumption of red wine is higher in france. the difference in regular red-wine consumption has been narrowing, but no similar convergence in heart-disease rates has occurred. which of the following, if true, most to account for the lack of convergence noted above? (a) consumption of saturated fats is related more strongly to the growth of fatty deposits on artery walls, which reduce blood flow to the heart, than it is to heart disease directly. (b) over the past 30 years, per-capita consumption of saturated fats has remained essentially unchanged in the united states but has increased somewhat in france. (c) reports of the health benefits of red wine have led many people in the united states to drink red wine regularly. (d) cigarette smoking, which can also contribute to heart disease, is only slightly more common in france than in the united states. (e) regular consumption of red wine is declining dramatically among young adults in france, and heart disease typically does not manifest itself until middle age.

(4.26) some studies have suggested that a nightly glass of wine may not only take the edge off a day but also improve health. is wine good for your health? a study of nearly 1.3 million middle- aged british women examined wine consumption and the risk of breast cancer. the researchers were interested in how risk changed as wine consumption increased. risk is based on breast cancer rates in drinkers relative to breast cancer rates in nondrinkers in the study, with higher values indicating greater risk. in particular, a value greater than 1 indicates a greater breast cancer rate than that of nondrinkers. wine intake is the mean wine intake, in grams per day, of all women in the study who drank the same amount of wine per week. here are the data ( for drinkers only): wine intakex( grams per day) 3 9.5 15 26 relative risky 1 .00 1.08 1.13 1.23 find the correlation r (â± 0.001) between wine intake and relative risk: r= do the data show that women who consume more wine tend to have higher relative risks of breast cancer? yes no
