Chapter 1, Problem 1.6.9(choose chapter or problem)
An ecologist tracked 290 zebra that were born in 2000. The number of zebra, z, living each subsequent year is recorded in Table 1.37. (a) Make a scatter plot of this data. Let t = 0 represent 2000. (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 zebra born in 2000 that are still alive.
