QUESTION 10 The results that you will be examining are based on data provided by USAID. The data showed the monetary amount of military assistance the United States provided to foreign countries since 1946, separated by country and by fiscal year. The original data set was published in the Greenbook (an annual report provided to Congress). Dollar values were adjusted for inflation and so they are referred to as "constant-dollars. Most values were large and represented using scientific notation. For example, a value of 6e9 corresponds to constant-dollars. Military assistance is generally based on events going on in specific parts of the world, but also relationships that we have with certain countries. We will assess the linear relationship between the amounts of assistance distributed in two specific years-2002 and 2010. Note that only those countries who have documented assistance for both years will be included in the analysis. a) Examine the scatterplot given below. Note that the point marked in pink is Afghanistan. FY2010 7e91 9. 5e9 4e91 3e9 2e9 1e9 5e8 2e9 19 1.5e9 FY2002 2.5e9 Why would Afghanistan be considered an outlier here? b) The correlation between FY2002 and FY2010 is r=0.4103. If Afghanistan is removed from the data set, we get the following scatterplot. FY2010 2.5e9 2e9 1.5e9 19te 5e8 588 2e9 2.5e9 1e9 1.5e9 FY2002 How would you describe the relationship between FY2002 and FY2010 now as compared to the relationship before Afghanistan was removed? Also, explain how the correlation value would change. c) Two additional outliers are Egypt and Israel. They are marked in pink in the first new scatterplot below. Once Egypt and Israel are removed, we get the scatterplot on that follows. FY2010 2.5e9 2e91 1.5e91 1e9 5e8 588 2e9 189 1.5e9 FY2002 2.5e9 FY2010 1e97 8e8 6e8 4e8 2e8 188 50000000 1.588 FY2002 Now, how would you describe the relationship between FY2002 and FY2010 with the three outliers removed? d) Can we assume that higher military spending in FY2002 will lead to higher military spending in FY2010? Why or why not? Your work can be typed or handwritten and must be neat. Submit it as a file (.docx, .pdf or a picture of handwritten work).
