Extrapolation. Your work in Exercise 7.36 no doubt included a regression line.Use the equation of this line to illustrate the danger of extrapolation, takingadvantage of the fact that the percent of grasslands burned cannot be less thanzero.Falling through the ice. The Nenana Ice Classic is an annual contest to guess theexact time in the spring thaw when a tripod erected on the frozen Tanana River nearNenana, Alaska, will fall through the ice. The 2005 jackpot prize was $285,000. Thecontest has been run since 1917. Table 7.4 gives simplified data that record only the dateon which the tripod fell each year. The earliest date so far is April 20. To make the dataeasier to use, the table gives the date each year in days starting with April 20. That is,April 20 is 1, April 21 is 2, and so on. You will need software or a graphing calculatorto analyze these data in Exercises 7.39 to 7.41.16
