K x, Number of Years after y, Population The population of a certain country from 1970 through 2007 1969 (millions) is shown in the table to the right Use your graphing utility's 1 (1970) 200.1 logarithmic regression option to obtain a model of the form 11 (1980) 230.6 y = a + b In x that fits the data. How well does the correlation 21 (1990) 241.6 coefficient, r, indicate that the model fits the data? 31 (2000) 275.3 38 (2007) 305.2 Obtain a model of the form y = a + b In x that fits the data y =0 (Round to three decimal places as needed.)
