the following data, N=_x_f

You were asked to help with an analysis of birth weights (BW) of 10,000 infants born in NYC during a certain period of time. The aim of the analysis is to see whether the birth weights of the infants are associated with mothers’ AGE at birth (continuous variable in years), mothers’ current HOUSING status (“own” and “not-own”; “own” is the reference group),  and NYC boroughs (the BOROUGH variable contains 5 categories “Manhattan”, “Bronx”, “Brooklyn”, “Queens” and “Staten Island”; “Manhattan” is the reference group). Write down the population model that estimates the effect of mother’s AGE on BW while adjusting for mother’s current HOUSING status. If you use dummy or binary variables, specify what they mean. Write down the population model that estimates the effect of mother’s AGE on BW while adjusting for mother’s current HOUSING status and BOROUGH. If you use dummy or binary variables, specify what they mean. Write down the population model that estimates the effect of mother’s AGE…

The following table was generated from the sample data of 1010 college students regarding the number of parking tickets the student receives in a semester, the student's age, and the student's GPA. The dependent variable is the student's GPA, the first independent variable (x1�1) is the number of parking tickets, and the second independent variable (x2�2) is the student's age.   Coefficients Standard Error t-Stat p-value Intercept −18.593656−18.593656 3.6727623.672762 −5.062581−5.062581 0.0038910.003891 Number of Parking Tickets 0.3232630.323263 0.0657790.065779 4.9144144.914414 0.0044190.004419 Student's Age 1.0181271.018127 0.1791910.179191 5.6817895.681789 0.0023530.002353 Copy Data Step 1 of 2 :   Write the multiple regression equation for the computer output given.
