3. Judge and Cable (2010) report the results of a study demonstrating a negative relationship between weight and income for a group of women professionals. Following are data similar to those obtained in the study. To simplify the weight variable, the women are classied into five categories that measure actual weight relative to height, from 1 = thinnest to 5 = heaviest. Income gures are annual income (in thousands), rounded to the nearest $1,000. Calculate the Pearson correlation for these data.
