Using the LIN regression, find the equation representing the best fit, in the form y=a+bx, where x=GDP/capita and y=telephone density. Find the coefficient of correlation. Use this equation to predict the telephone density of a country with a GDP per capita of $10 695. If a country has a telephone density of 5.68, what GDP

per capital would you expect this country to have?
