The number of patients classified with hypertension (high blood pressure) is 418. The department of Health and Human services has a target of 36% for hypertension prevalence. Based on the 95% confidence interval, is there any evidence to suggest that the prevalence of hypertension is different from the target value? Let p be the true proportion of adult Americans with hypertension. Answer choice: 95% CI: (0.3801, 0.4263), there is not sufficient evidence to suggest that p is different from 0.36. 95% CI: (0.3801, 0.4263), there is evidence to suggest that p is different from 0.36. 95% CI: (0.3513, 0.4087), there is not sufficient evidence to suggest that p is different from 0.36. 95% CI: (0.3513, 0.4087), there is evidence to suggest that p is different from 0.36.A pharmaceutical company is running tests to see how well its new drug lowers cholesterol. Fourteen adults volunteer to participate in the study. The total cholesterol level of each participant (in mg/dL) is recorded once at the start of the study and then again after three months of taking the drug. The results are given in the following table. Construct a 90% confidence interval for the true mean difference between the cholesterol levels for people who take the new drug. Let Population 1 be the initial cholesterol level and Population 2 be the cholesterol level after three months. Round the endpoints of the interval to one decimal place, if necessary.
