Question
Transcribed Image Text:According to an article, one may be able to predict an individual's level of support for ecology based on demographic and ideological characteristics. The multiple
regression model proposed by the authors was the following.
y = 3.60-.01.x₁ +.01.x2-.07x3+.12x4+.02xs-.04x6-.01x7.04x8-.02xg+e
The variables are defined as follows.
y = ecology score (higher values indicate a greater concern for ecology)
x₁ = age times 10
x₂ = income (in thousands of dollars)
x3 = gender (1 = male, 0 = female)
X4 = race (1 = white, 0 = nonwhite)
X5 = education (in years)
x6 = ideology (4 = conservative, 3 = right of center, 2 = middle of the road, 1 = left of center, and 0 = liberal)
X7 = social class (4 = upper, 3 = upper middle, 2 = middle, 1 = lower middle, 0 = lower)
x8 = postmaterialist (1 if postmaterialist, 0 otherwise)
x9 = materialist (1 if materialist, O otherwise)
(a) Suppose you knew a person with the following characteristics: a 30 year old, white female with a college degree (20 years of education), who has a
$39,000 per year job, is from the upper middle class and considers herself left of center, but who is neither a materialist nor a postmaterialist. Predict her
ecology score.
