Fit a regression line to the data shown in the chart, and find the coefficient of correlation for the line. Use the regression line to predict life expectancy in the year 2000, where x is the number of decades after 1900. year, x 0 (1900) life expectancy, y 49.1 years 2 (1920) 51.4 years 4 (1940) 6 (1960) | 8 (1980) 53.0 years 54.2 years 55.2 years Choose the regression line. OA. y = 0.750x - 49.58 OB. y = 49.58x + 0.750 OC. y = 0.750x + 49.58 OD. y = 49.58 The life expectancy in the year 2000, rounded to one decimal place is [ years.
