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

a) 0.46

b) (2341.39, 3230.61)

c) For those Russians who do smoke, estimate the number of cigarettes smoked per day.= 23

Step-by-step explanation:

check below for more detailed solution

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
