Consider the econometric model y=0+1x+u. After estimation, we obtain that 1=0.5. We also know that the variance of x is equal to 5 and the variance of y is equal to 10. Consider a second econometric model x=+ny+c. The estimated value of n is: 13 in the pare Consider the econometric model y=+1z+14. After estimution we obtain that 1=0.5. We alioknow that the variance of x is equal to 5 and the variancr of y is equat to 10 Consider a second econometric model z=70+7iy+c. The estimated vilue of n is: 0.25 0.1 0.05
