Question

A study was conducted to determine if a person's agreeability (whether they are generally an agreeable person or not) affects their income level. It also looked at the person's gender to see if it was a factor as well. The variables are shown below: Income: y annual income in dollars Agree: x1 agreeability level with higher scores indicating a person is more aggregable and lower scores indicating less agreeable Gender: x2-1 if male, 0 if female Use the following information to answer the multiple regression questions. Printout A: Pairwise Correlations: Income Agree Agree -0.2785 1.0000 Gender 0.8327 -0.0478 Printout B: Best Subset Regression Models for Income Forced Independent Variables: A)Agree (BIGender (C)x1x2 Unforced Independent Variables: (DIx1sq (E)x15qx2 Adjusted AICc P Cp RSquare Min AIC F P(F) Variables 4 4.6 0.7552 1798.32 5.805E+09 A BC 5 4.0 0.7593 1797.84 5.648E+09 264 0.1075 ABCD 5 5.3 0.7560 1799.22 5.726E+09 1.30 0.2568 A BCE 6 6.0 0.7568 1800.15 5.648E 09 3.31 0.0356 ABCDE Cases Included 100 Missing Cases 0 Fill in the blank The results shown on Printout B above lead us to conclude that there is (at alpha .05). o insufficient evidence of interaction between income and agreement score. e sufficient evidence of interaction between income and agreement score. insufficient evidence of a statistically useful model for income insufficient evidence of curvature relating income to agreement score. o sufficient evidence of curvature relating income to agreement score.
