You wish to know whether, on average, peoples' level of concern about climate change is related to the number of miles they have flown on airplanes for non-business reasons in the past year and their political orientation. You draw a random sample and ask each person three questions: (1) "on a scale of 0 (not at all concerned) to 10 (very concerned), how concerned are you about climate change?", (2) "how many miles have you flown on airplanes for non-business reasons in the past year?", and (3) "on a scale of -3 (very conservative) to +3 (very liberal), where does your political orientation fall?" The two simple linear regressions yielded: bl values of -,0002 for miles (p .02) and 1,2 (p=.03) for political orientation; a coefficient of determination of ,15 for miles and , 10 for political orientation; an adjusted coefficient of determination of . 13 for miles and ,08 for political orientation; Global F p-values of ,04 for miles and ,06 for political orientation. The multiple regression yielded: An intercept of 5,00; b values of -,0001 for miles (p-,06) and 1,0 (p .04) for political orientation; a coefficient of determination of ,20; an adjusted coefficient of determination of ,15; a Global F p-value of,04 Based on these data: 1 1. What is the value of the coefficient of partial determination for Miles? (provide a value) How did you derive this value
