3.Measurement Error on x;Imagine you want to estimate the following model:Yi = B1 + B2x; + Ei,where Ele,x:] = 0. The issue is that you do not observe , but observeT: = x + wi, where the measurement error, wi, is such that Elwr] = 0, andcov(wi, ei] = 0. You estimate:Yi = B1 + B2ai + vịby OLS. Show thatplim(b2) =o? + o%where o? = var(x;) and o =var(w;).%3D

Please answer from question 4 to last questionMy answers from question 1 to 3 are at the end Sarah wants to estimate the relationship between individual earnings in the labour market (earn) and years of education achieved (educ). She collects data from a sample of 122 individuals on their monthly salaries (Y), measured in rands, and education levels (X), measured in years of education.Based on these data, she derives the following estimates: ∑XY=41421943.8∑X2=15472∑X=1242∑Y=3401031 Question 1 The value for the slope parameter is ?

Can balloons hold more air or more water before bursting? A student purchased a large bag of 12-inch balloons. He randomly selected 10 balloons from the bag and then randomly assigned half of them to be filled with air until bursting and the other half to be filled with water until bursting. He used devices to measure the amount of air and water was dispensed until the balloons burst. Here are the data

Hello. I am having a hard time understanding and solving this problem. Can I ask for help how? Here is the problem. The director of an alumni association for a small college wants to determine whether there is any type of relationship between the amount of an alumnus’s contribution (in dollars) and the number of years the alumnus has been out of school. The data follow. Solve the correlation r and find the y’ when x = 4 years. I have also attached the image of the correlation data.
