Considering the following economic model of wages and education: wage-b0+b1educ+u, where wage is the individuals hourly wage, educ is the individual's years of schooling, u is the error and b0 and b1 are population parameters Do you expect b1 to be positive or negative. Explain your answer. [2 points] Explain intuitively how an OLS regression fits the relationship between wage and education. [3 points) ii. Showing all of your working, derive the OLS estimators of b0 and b1. [6 points]

Suppose you are interested in studying the factors that influence wages. You plan on using a multiple regression model with k = 3 explanatory variables. In particular, you plan on estimating: wage = Bo + Bieduc + Bzexper+Bz age where wage = hourly wage in dollars educ = years of education exper = years of work experience age = age, in years An alternative way of estimating Ba would be to regress wage on re , (wage; = Bo +...

Suppose that you want to estimate the relationship between people's weight (W) and the number of times they eat out in a month (EO) where Ao is the intercept of the population regression line: β1 is the slope of the population regression line; ui įs the error term; and the subscript i runs over observations, i= 1, ' n For this, you collect data rom a random sample 01250 people. After anal zing he data, you determin na the c...

Consider the relationship between hourly wage rate and education attainment. A random sample of 21 male workers was collected to estimate the following model Y; = Bo + B1X; + uj, for i = 1,..., 21. Here, Y; is the logarithm of hourly wage rate, log(wage), for the i-th worker. Xi is the education level, husedu, of the i-th worker, which is measured as the years of schooling, and uị is the error term for the i-th worker. The ordinary...

You are interested in the relationship between education and income. Your intercept is $6,000 and your slope is $1,500. How many absences from work would we expect to see for a person with two children? (Round to one decimal place)

You are interested in the relationship between income and height. To estimate this relationship, you take one llect data on their height and income. You then collect another random sample of 50 workers, collecting data on their height and income. You run two separate regressions, one in each sample. Which of the following statements is true?. O The R squared in both regressions will be the same. O The value of the slope parameter in both regressions will be the...

ante 7. You are a researcher interested in the relationship between age of an infant (in months) and hours spent sleeping. Suppose that you sampled N - 10 infants between the ages of 1 - 12 months. After fitting a simpler linear regression model, you found that the intercept of your begression line was 14.72 and the slope was 0.24. (a) Write the regression equation for predicted scores. Include the parameter estimates and informative labels (i.e., use 14.72,-0.24 hours sleep,...
