Every April, The Masters—one of the most prestigious golf tournaments on the PGA golf tour—is played in Augusta, Georgia. In 2013, 60 players received prize money. The 2013 winner, Adam Scott of Australia, earned a prize of $1,440,000. Miguel Cabrera finished in second place, earning $864,000. Jason Day finished in third place, earning $544,000. The data are briefly summarized below. Each player has three corresponding variables: finishing position or rank, score, and prize (in dollars). The complete file is in the data sets available on the text website, www.mhhe.com/lind16e, labeled as Ex13-36. We want to study the relationship between score and prize.
a. Using Score as the independent variable and Prize as the dependent variable, develop a scatter diagram. Does the relationship appear to be linear? Does it seem reasonable that as Score increases the Prize decreases?
b. What percentage of the variation in the dependent variable, Prize, is accounted for by the independent variable, Score?
c. Calculate a new variable, Log-Prize, computing the log to the base 10 of Prize. Draw a scatter diagram with Log-Prize as the dependent variable and Score as the independent variable.
d. Develop a regression equation and compute the coefficient of determination using Log-Prize as the dependent variable.
e. Compare the coefficient of determination in parts (b) and (d). What do you conclude?
f. Write out the regression equation developed in part (d). If a player shot a total of 2
