Among 1,105 snorers in the study, 89 had heart disease, while only 29 of 1,379 nonsnorers had heart disease. Determine a 95% confidence interval that estimates p1 − p2 = difference in proportions of snorers and nonsnorers who have heart disease. (Let p1 be the proportion of snorers and p2 be the proportion of nonsnorers. Round your answers to three decimal places.) ____to ____A survey of 300 union members in New York State reveals that 112 favor the Republican candidatefor governor.

This estimate was based on a random sample of 2001 U.S. adults! Construct and interpret a 95% confidence interval for the proportion of all U.S. adults who play video games. O We are 95% confident that the interval from 0.472 to 0.509 captures p = the proportion of adults in the Pew Research Center report who play video games. O We are 95% confident that the interval from 0.472 to 0.509 captures p = the true proportion of U.S. adults who play video games. We are 95% confident that the interval from 0.468 to 0.512 captures p = the true proportion of U.S. adults who play video games. O We are 95% confident that the interval from 0.468 to 0.512 captures p= the proportion of adults in the Pew Research Center report who play video games.

- According to the website www.collegedrinkingprevention.gov, "About 25 percent of college students report academic consequences of their drinking including missing class, falling behind, doing poorly on exams or papers, and receiving lower grades overall." A statistics student is curious about drinking habits of students at his college. He wants to estimate the mean number of alcoholic drinks consumed each week by students at his college. He plans to use a 90% confidence interval. He surveys a random sample of 63 students. The sample mean is 3.7 alcoholic drinks per week. The sample standard deviation is 3.2 drinks. Construct the 90% confidence interval to estimate the average number of alcoholic drinks consumed each week by students at this college. 1. The t value is - 2. The standard error has a value of -- 3. The margin of error has a value of 4. Construct the 90% confidence interval to estimate the average number of alcoholic drinks consumed each week by students at this college.A study of 420,039 cell phone users found that 131 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0443% for those not using cell phones. Complete parts (a) and (b). ..... a. Use the sample data to construct a 95% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system. • D%A team of researchers aims to understand whether a sleep treatment drug has an effect on the number of hours of REM sleep. Five subjects were randomly selected and their time in REM sleep (in minutes) was measured before treatment and after treatment. The before treatment measurements are: (30, 45, 90, 60, 100). The after-treatment measurements for the same five patients are: (35, 30, 80, 70, 110). The researchers compute a 99% confidence interval for the difference (after treatment minus before treatment) in REM sleep time. What is the lower bound of this interval?A study of 420,097 cell phone users found that 137 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0311% for those not using cell phones. Complete parts (a) and (b). .... a. Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system. %After surveying a random sample of 300 students in an online degree program, 86% believed that their classes were worth the cost they were paying. The results from a survey of 345 randomly selected students who were in a face-to-face degree program who had also taken some online courses, showed that 84% of them believed those online courses were worth the cost. Construct a 90% confidence interval for the difference between the two groups of students.A study of 420,064 cell phone users found that 136 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0343% for those not using cell phones . Use the sample data to construct 95% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system.Recommended textbooks for youMATLAB: An Introduction with ApplicationsStatisticsISBN:9781119256830Author:Amos GilatPublisher:John Wiley & Sons Inc
