Nikita extracted the model, Y = 0.5 + 0.75X, from the output of a simple regression analysis. All the coefficients had a p-value less than 0.05. This implies that Oa. a high coefficient of determination Ob. a unit increase in Y will result in a 0.75 unit increase in X O c. a strong correlation between X and Y O d. a unit increase in X will result in a 0.75 unit increase in Y
