thank you

In a simple baseline/offset model y = 60 + b1'x with a dummy-variable (0 or 1) predictor x, the coefficient b1 may be interpreted as which of the following? O the predicted value of the outcome variable when the dummy variable is equal to 0. O the change in y associated with a one-standard deviation change in . O the improvement in R-squared that we get from including x in the model O the change in the expected value of y from the x-D case to the wol case. O the expected outcome when the dummy variable equal to 1. as opposed to Q O the predicted value of the outcome variable when the dummy variable is equal to 1
