Let x represent per cаpitа incоme in thоusаnds оf dollars, and let y represent the number of medical doctors per 10,000 residents. Six small cities gave the following information. Data Table Income, x 8.4 9.2 10.2 8.3 8.3 8.8 # Doctors, y 9.6 18.7 20.8 10.1 11.4 13.1 Calculate the value of the correlation coefficient (round to three decimal places). [r] Is there a significant correlation between x and y? (yes or no) [sign] Calculate the value of the coefficient of determination (round to three decimal places). [r-sq] Find the equation of the least-squares regression line (round each coefficient to three decimal places). y = [a] + [b]x Predict the number of medical doctors per 10,000 residents for a small city that has a per capita income of 9.5 thousand dollars (round to the same number of decimal places as y).
