3. Consider the following sets of data from Dataset II. For the dataset, determine what type of chart or graph would best represent those data (A-D). Explain your reasoning in detail. Pie chart Line graph Bar graph Scatter plot Dataset II: Carolyn collected data on rates of recycling participation over the last eight years to determine whether her city’s education program has been effective. In 2006, before the education program was implemented, 9% of the city’s residents recycled. Her data follows:   Year Participation Rate 2006 9% 2007 13% 2008 17% 2009 22% 2010 28% 2011 31% 2012 32% 2013 30% 2014 31%

Consider the bar graph below, which shows average milk prices in four different cities in the United States. What is wrong with this graph? What poor conclusion(s) could be drawn by someone who isn't familiar reading this kind of graph? What could be done to better represent this data? Outrageous Milk Prices in Philadelphia 5.00 4.50 4.00 3.50 Philadelphia Sacramento Oklahoma Indianapolis City Milk Price (dollars/gallon)

An economic organization tracks summary statistics of various countries. These include GDP (gross domestic product per capita) and trade balances (measured as a percentage of GDP). Exporting countries tend to have large positive trade balances. Importers have negative balances. The data are shown in the accompanying table. Formulate the SRM with GDP as the response and Trade Balance as the explanatory variable. Complete parts (a) through (c) below. Click the icon to view the data table. (a) Country X reported the highest positive balance of trade, 24.2% of GDP and per capita GDP equal to $63,000. Fit the least squares equation both with and without country X and compare the results. Does the fitted slope change by very much? Find the least squares equation without country X. Complete the equation below. Estimated GDP ($ per cap) = ☐ ☐ Trade Bal (%GDP) (Round to the nearest integer as needed.) Data Table - X Trade Balance (%GDP) GDP ($ per capita) -6.3 16,876 15.7 44,932 -0.9 9,334 -7.9…
