Q1 The following table is a summary of data points. : work experience in years Observation 1 Observation 2 Observation 3 Y: wealth Observation 5 We are interested in the population regression line, Y: = 50 +51Xi +ui- Q1.1 Calculate [30 and 31. \fQl.4 Now, say that years of experience become halfyear of experience, meaning you have to multiply 2 to all X,-. What happens to the estimator, 31, and what happens to R2? Ql.5 Now, say that we do not have 81 in our population regression line. Yr =o+ur Using the table given in Q1, calculate 0 for this case. 01.6 Now, say that we do not have [30 in our population regression line. Y: = 31X: + \"1'- Using the table given in Q1, calculate 31 for this case. 01.7 What is different with having [30 conceptually
