## Question

###### A study was conducted to study college students who smoke tofind if there was a relationship was between number of cigarettessmoked per day and parental smoking status. The studyrecruited 300 college students who currently reportedsmoking. In the study, the adult children of smokers smokedapproximately 4 cigarettes more per day than the adult children ofnon-smokers. The 95% confidence interval for the differencewas 3.4 to 5.3 cigarettes per day. If we wanted to reduce thesize of our confiden

A study was conducted to study college students who smoke to find if there was a relationship was between number of cigarettes smoked per day and parental smoking status. The study recruited 300 college students who currently reported smoking. In the study, the adult children of smokers smoked approximately 4 cigarettes more per day than the adult children of non-smokers. The 95% confidence interval for the difference was 3.4 to 5.3 cigarettes per day. If we wanted to reduce the size of our confidence interval (that is, reduce the width), which of the following would help? Select all that apply. A. None of these will have an impact on the size of the confidence interval. B. Recruit more college students to participate in our study. C. Perform a new study with less college students. Redo the study with the same number of adults, but include more than just college students. None of these will have an impact on the size of the confidence interval. D. We could calculate the 99% confidence interval instead. E. We could calculate the 90% confidence interval instead. F. Redo the study with the same number of adults, but include more than just college students. #### Similar Solved Questions
