Use technology to determine the correlation coefficient, rounded to two decimal places, between the percentage of people in a country who are literate and the percentage who are undernourished. Use technology to find the equation of the regression line for the percentage who are literate and the percentage who are undernourished. Round "m" and "b" to two decimal places. Use technology to determine the percentage of people, to the nearest percent, can we anticipate are undernourished in a country where 60% of the people are literate?
