A study tests the effect of earning a Master’s degree on the salaries of professionals. Suppose that


A con-over criterions the pi of achieveing a Master's station on the salaries of professionals. Suppose that the salaries of the professionals (S;) are not subject on any other inconstants. Let D; be a inconstant which takes the like 0 if an separate has not achieveed a Master's station, and a like 1 if they possess achieveed a Master's station. What would be the retrogression pattern that the researcher wants to criterion? A. S;= Bo + B4D; + uj, i = 1, ... , n. OB. 1 = Bo + B1 S; + U;, i = 1, ..., n. O C. O = Bo + B4S; + Uj, i = 1, ... , n. OD. S; = Bo + B1 + Uj, i = 1, ... , n. Suppose that a accidental pattern of 160 separates suggests that professionals outside a Master's station achieve an middle stipend of $62,000 per annum, timeliness those after a while a Master's station achieve an middle stipend of $80,000 per annum. The OLS like of the coefficient B1 succeed be $ and that of Bo succeed be $0.
