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) 203.3 logarithmic regression option to obtain a model of the form 11 (1980) 226.5 y = a + b In x that fits the data How well does the correlation 21 (1990) 248.7 coefficient, r, indicate that the model fits the data? 31 (2000) 281 4 38 (2007) 300.9 Obtain a model of the form y = a + b In x that fits the data. y= (Round to three decimal places as needed.)
