Human capital theory suggests that those who have invested in higher levels of education will be able to command higher wages. A labour economist collected data on annual wages (Y, in $'000) and years of study (X) from a random sample of 12 employees to test this proposition. Assuming a linear relationship between Y and X, the labour economist used a least-squares method and found that the Y intercept = -23.50 and the slope = 9.73. Also, the sum of squares total (SST) and the sum of squares regression (SSR) were equal to 11132.92 and 8726.91, respectively. What is the lower bound of a 95% prediction interval of annual wages (in $'000) for an employee with 10 years of study. Assumer the h Statistic is 0.10. a. greater than $20 but less than $36 b. less than $20 c. greater than $20 but less than $30 d. greater than $36

Human capital theory suggests that those who have invested in higher levels of education will be able to command higher wages. A labour economist collected data on annual wages (Y, in $'000) and years of study (X) from a random sample of 12 employees to test this proposition. Assuming a linear relationship between Y and X, the labour economist used a least-squares method and found that the Y intercept = -23.50 and the slope = 9.73. The labour economist also found that the standard error of the slope was 1.61. Based on this information, what statistical decision would you made if you are testing the null hypothesis that there is no linear relationship between the two variables, X and Y? a. Accept the null hypothesis. b. Reject the null hypothesis. c. Do not reject the null hypothesis. d. Reject the alternative hypothesis.

Based on this information, what is the upper critical value used to test the null hypothesis that there is no linear relationship between the two variables, X and Y at the 1% level of significance?

Which of the following is a prediction of human capital theory?Question 11Answera.The value of an individual's skills and abilities is a function of the time and expense required to acquire them.b.Higher wages improve efficiency by attracting workers who will perform better.c.Jobs with negative characteristics require higher pay to attract workers.d.Pay policies signal the kinds of behaviour an employer seeks from employees.e.Job seekers will not accept jobs when pay is below a certain wage.

A consumer's spending is widely believed to be a function of their income. To estimate this relationship, a university professor randomly selected 19 of his students and collected information on their spending (Y, in dollars) and income (X, in dollars) patterns in week 6 of the semester. Assuming a linear relationship between Y and X, the professor used the least-squares method and found that the Y intercept = 20.90 and the slope = 0.66. Also, the sum of squares total (SST) and the regression sum of squares (SSR) were equal to 65600.74 and 52831.23, respectively. What is the upper bound of a 95% prediction interval for a student's spending on a weekly income of $60. Assume the h Statistic equals 0.12. a. greater than $80 but less than $120 b. greater than $100 but less than $120 c. greater than $120 d. less than $100
