When z-scores are used in a regression model, the betas will be exactly the same as the unstandardized slopes. This is because z-scores standardize the variables by converting them to a common metric with a mean of 0 and a standard deviation of 1, allowing for a direct comparison of their effects on the dependent variable. Therefore, the betas (which represent the change in the dependent variable for a one-unit change in the independent variable) will be equivalent to the unstandardized slopes.
