Chapter , Problem 1.6.10(choose chapter or problem)
An ecologist tracked 290 topi that were born in 2004. The number of topi, , living each subsequent year is recorded in Table 1.38. (a) Make a scatter plot of this data. Let = 0 represent 2004. (b) Draw by eye a line of good fit and estimate its equation. (Round the coefficients to integers.) (c) Use a calculator or computer to find the equation of the least squares line. (Round the coefficients to integers.) (d) Interpret the slope and each intercept of the line. (e) Interpret the correlation between the year and the number of topi born in 2004 that are still alive. Table 1.38 Year 2004 2005 2006 2007 2008 2009 2010 2011 2012 Topi 290 288 268 206 140 90 64 44 8
