Since the Great Depression of the 1930s. the link between the suicide rate and the state of the economy has been the subject of much research. Research exploring this link using regression analysis was reported in the Journal of Socio-Economics (Spriny. 1992). The researchers collected data from a 45-year period on the following variables:

y = Suicide rate

x₁ = Unemployment rate

x₂ = Percentage of females in the labor force

x₃ = Divorce rate

x₄ = Logarithm of Gross National Product (GNP)

x₅ = Annual percent change in GNP

One of the models explored by the researchers was 7 multiple regression model relating y to linear terms 111 x, through x5. The least squares model below resulted (the observed significance levels of the /3 estimates. are shown in parentheses beneath the estimates)

a. Interpret the value of R². Is there sufficient dence to indicate that the model is useful for pret dicting the suicide rate? Use a = .05

b. Interpret each of the coefficients in the model, and each of the corresponding significance levels.

c. Is there sufficient evidence to indicate that the un employment rate is a useful predictor of the suicide rate? Use a = .05
