The following two equations describe property crime and police expenditures across U. S. cities: Crimei 5 a0 1 a1Policei 1 a2Incomei 1 u1,i Policei 5 b0 1 b1Crimei 1 b2Incomei 1 b3Liberali 1 u2,1 Crime i 5 Number of crimes committed in city i last year Police i 5 Total spending on the police force in city i last year Income i 5 Average income in city i last year Liberal i 5 Share of votes received by the liberal presidential candidate from city i in the last election a. If you were to estimate these two equations with OLS, would you get consistent estimates? Why or why not?
b. Which of the two equations is fully identified? How do you know this?
c. Describe how you would estimate one or both of the equations using 2SLS. Describe the properties of the estimates in both equations.
(All questions should be solved)

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

c > -10.55

step-by-step explanation:

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
