Explore! Exercises 9 and 10 provide two data sets from “Graphs in Statistical Analysis," by F. J. Anscombe, the American Statistician, Vol. 27. For each exercise, a. Construct a scatterplot. b. Find the value of the linear correlation coefficient r, then determine whether there is suffi- cient evidence to support the claim of a linear correlation between the two variables. c. Identify the feature of the data that would be missed if part (b) was completed without con- structing the scatterplot. 9. 10 8 13 11 14 6. 4 12 7 y 9.14 8.14 8.74 8.77 9.26 8.10 6.13 3.10 9.13 7.26 4.74
