Nation: U.S.A. U.K. Germany France Norway Sweden

Taxes (% of GDP), x 27.3 37.0 38.8 44.0 44.3 51.3

Infant Mortality Rate, y 6.30 4.93 4.03 3.36 3.61 2.75

a)Use either R to create a scatter plot of Infant Mortality Rate (y) versus Taxes (x). Copy and paste it into to document you turn in.

b)Find the equation of the least squares regression line relating Infant Mortality Rate (y) to Taxes (x).

c)Find and interpret the coefficient of determination (aka R-squared) for your regression equation in part b).
