Question

Imports and Exports A random sample of countries shows the value of U.S. exports and the U.S. imports for each country for a recent year. The data are in hundreds of millions of dollars. Assume the independent variable is exports. Country 1 2 3 4 5 6 7 8 9 10 11 Exports 45 46 12 44 34 30 12 9 35 47 36 Imports 44 43 18 40 32 27 13 11 33 45 31 Send data to Excel The correlation coefficient for the data is $r = 0.986$ and $\alpha = 0.05$. Should regression analysis be done? The regression analysis should not be done. The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places. $y'=a+bx$ a = b= Find $y'$ when $x = 23$ hundred million dollars. Round to one decimal place. $y'=$
