In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 337 trials, the touch therapists were correct 163 times. Using Emily's sample results, construct a 95% confidence interval estimate of the proportion of correct responses made by touch therapists. (round to 3 decimal places)
The NCHS reported that the mean total cholesterol level was 203 for all adults in 2003. Patients (n=15) were enrolled in a 6-week study to test the efficacy of a new drug. Use the five-step hypothesis testing procedure to determine if the new drug was effective in reducing the cholesterol levels compared to the historical mean. At the end of 6 weeks: ◦n = 15 ◦X ̅ = 195.9 ◦s = 28.7

A study was done to determine whether there is a relationship between snoring and the risk of heart disease. Among 1,105 snorers in the study, 85 had heart disease, while only 21 of 1,379 nonsnorers had heart disease. In USE SALT (a) Determine a 95% confidence interval that estimates p, - p2 difference in proportions of snorers and nonsnorers who have heart disease. (Let p, be the proportion of snorers and p, be the proportion of nonsnorers. Round your answers to three decimal places.) |-0.079 X to -0.045
