Russia has recently started a push for stronger smoking regulations much like those in western countries concerning cigarette advertising, smoking in public places, etc. The WEBfile named Russia contains sample data on smoking habits of Russians that are consistent with those reported by The Wall Street Journal (The Wall Street Journal, October 16, 2012). Analyze the data using Excel and answer the following questions. Click on the webfile logo to reference the data.

a. Develop a point estimate and a 95% confidence interval for the proportion of Russians who smoke. Round point estimate to two decimals and confidence interval to four decimal places.
b. Develop a point estimate and a 95% confidence interval for the mean annual per capita consumption (number of cigarettes) of a Russian. If required, round your answers to nearest whole value.
c. For those Russians who do smoke, estimate the number of cigarettes smoked per day. If required, round your answer to nearest whole value.

High school seniors with strong academic records apply to the nation’s most selective colleges in greater numbers each year. because the number of slots remains relatively stable, some colleges reject more early applicants. suppose that for a recent admissions class, an ivy league college received 2851 applications for early admission. of this group, it admitted 1033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. in the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. counting the students admitted early and the students admitted during the regular admission process, the total class size was 2375. let e, r, and d represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool. suppose a student applies for early admission. what is the probability that the student will be admitted for early admission or be deferred and later admitted during the regular admission process?
