Question description

For the question, consider the following sample regression line:  Salaryi = 50 + 3educi − 1.2experiencei  Salary is measured in thousands of dollars and education and experience are both measured by numbers of years. Assume that the standard errors for the coefficient estimates are .5 for education and 1.5 for experience. Additionally, assume R2=.57 and R¯2=.54. The estimates come from a sample of 12 observations (assume that the error term for the regression is normally distributed). (c) Conduct a positive, right-tailed hypothesis test for the coefficient estimate on education at the 99% level of confidence. Show all steps and be sure to interpret your results.  (d) Conduct a two-tailed hypothesis test for the coefficient estimate on experience at the 95% level of confidence. Show all steps and be sure to interpret your results.  (e) Construct a 95% confidence interval for the coefficient on education.
