9. Gravetter/Wallnau/Forzano, Essentials - Chapter 14 - End-of-chapter question 9 Judge and Cable (2010) report the results of a study demonstrating a negative relationship between weight and income for a group of men. Following are data similar to those obtained in the study. To simplify the weight variable, the men are classified into five categories that measure actual weight relative to height, from 1 = thinnest to 5 = heaviest. Income figures are annual income (in thousands), rounded to the nearest $1,000. Weight (X) Income (Y) 4 151 5 88 3 52 2 73 1 49 3 92 1 56 5 143 Calculate means and standard deviations for each of the above variables (data are for a sample) Calculate r using the computational formula Interpret r for degree and direction Calculate the linear equation Calculate b Calculate a Calculate radj Calculate sy|x
