The slope βS1U1B11 is a parameter, which represents a fixed, unknown value that describes the true relationship between the predictor variable x and the response variable y. It is not a random variable, a statistic, or assumed to be distributed normally. The error term εS1U1B1iS1U1B0 may be a random variable with certain assumptions, but it is not the slope itself.
