The Hаppy Plаnet Index The website TED.cоm оffers free shоrt presentаtions, called TED Talks, on a variety of interesting subjects. One of the talks is called “The Happy Planet Index,” by Nic Marks.66 Marks comments that we regularly measure and report economic data on countries, such as Gross National Product, when we really ought to be measuring the well-being of the people in the countries. He calls this measure Happiness, with larger numbers indicating greater happiness, health, and well-being. In addition, he believes we ought to be measuring the ecological footprint, per capita, of the country, with larger numbers indicating greater use of resources (such as gas and electricity) and more damage to the planet. Figure 2.58 shows a scatterplot of these two quantitative variables. The data are given in HappyPlanetIndex. 8 pts Figure 2.58 Happiness and ecological footprinthappy planet(1).png Does there appear to be a mostly positive or mostly negative association between these two variables? __________________________ Describe the happiness and ecological footprint of a country in the bottom left of the graph. a. happy, low ecological footprint b. happy, high ecological footprint c. not happy, low ecological footprint d. not happy, high ecological footprint Answer: Costa Rica has the highest Happiness index. Estimate its ecological footprint score. (1 decimal place) Answer: _ For ecological footprints between 0 and 6, does a larger ecological footprint tend to be associated with more happiness? ( yes or no) Answer: What about for ecological footprints between 6 and 10? (yes or no) Answer: _ Marks believes we should be working to move all countries to the top left of the graph, closer to Costa Rica. What attributes does a country in the upper left of the graph possess? a. happy, low ecological footprint b. happy, high ecological footprint c. not happy, low ecological footprint d. not happy, low ecological footprint Answer: If the goal is to move all countries to the top left, how should efforts be directed for those in the bottom left? a. improve happiness and well-being b. reduce happiness and well being c. increase ecological footprint d. reduce ecological footprint e. no change, leave as is Answer:_ How should efforts be directed for those in the top right? a. improve happiness and well-being b. reduce happiness and well-being c. increase ecological footprint d. reduce ecological footprint e. no change, leave as is Answer:_____

Twо vаriаbles in the dаtaset AllCоuntries are the size оf the country (in 1000 sq km) and the percent of the population living in the rural areas. We are interested in using the size of the country (Land Area) to predict the percent rural (Rural). The values of these variables for a random sample of ten countries is shown, with the 3-letter country codes, in the table. A scatterplot is shown for the data. 12 pts Country SRB BHS SVN UZB TUN ARM ROU MKD LBN PRK Land Area 87.46 10.01 20.14 425.40 155.36 28.47 230.02 25.22 10.23 120.41 Rural 44.6 17.3 50.2 63.8 33.5 37.0 45.8 43.0 12.5 39.4 all countries(1).png a. What is the explanatory variable? a. Rural b. Land Area Answer: _____ b. Without doing any calculations, which do you think is the most likely correlation between the two variables? a. -0.60 b. 60 c. 0.00 d. 0.60 Answer: _ c. Use technology to find the regression line to predict percent rural from land area. Round your answer for the intercept to two decimal places and your answer for the slope to three decimal places. rural = + (land area) d. Does the intercept make sense in this situation? a. Yes b. No Answer: e. Which country is the most influential on this regression line (use the 3 letter code) _ f. Use the regression line to predict the percent of the US population living in rural areas given that the area of the US is 9145.4 thousand sq km. Round your answer to two decimal places. Predicted percent of the US population living in rural areas = % Does the prediction seem reasonable? Answer: ___(Yes or No)

Mаjоr Leаgue Bаseball is split intо twо leagues, the National League (NL) and the American League (AL). The main difference between the two leagues is that pitchers take bats in the National League but not in the American League. Two of the variables in the BaseballHits dataset are the number of wins and the number of runs scored during the season. The dataset consists of values for each variable from all 30 MLB teams. From these data we calculate the regression line: 10 pts Wins = 34.85 + 0.070(runs) a. Which is the explanatory variable in this regression line? a. Wins b. Runs Answer: _ b. Interpret the slope in context. a. The expected number of runs given one win. b. The expected number of wins given one run. c. The expected change in number of runs given one more win. d. The expected change in number of wins given one more run. Answer: c. The San Francisco Giants won 88 games while scoring 665 runs in 2014. Predict the number of games won by San Francisco using the regression line. Round your answer to one decimal place. Wins = _ Calculate the residual. Round your answer to one decimal place. Residual = _ Were the Giants efficient at winning games with 665 runs? Choose the answer in accordance to (c) of the question statement Answer: _(Yes or No)
