The regression equation is given by y = 0.348 + 0.495*X.
The slope is 0.495. With one unit increase in X, there is 0.0495 units increase in Y. In this case, with one unit increase in the percentage of African Americans in the population, there isÂ 0.0495 increase in the percentage of seats on the City Council that are held by African Americans.
The intercept is 0.348. The initial value of Y is 0.348 when x is equal to zero.Â The initial value of the percentage of seats on the City Council that are held by African Americans is 0.348 only when the percentage of African Americans in the population is 0%. There seems to be no practical significance of this result.
Coefficient of determination, R^2 = 34%. There is 34% variation in Y (percentage of seats on the City Council that are held by African Americans) which is explained by the independent variable X (the percentage of African Americans in the population).Â
Null hypothesis,...
