The standard error of the regression (SER) is 580.4. What are the units of measurement for the SER? O A. Unit-free. O B. Dollars per week. O C. Dollars per year. O D. Dollars. The regression R is 0.021. What are the units of measurement for the R? O A. Dollars. O B. Dollars per year. O c. Unit-free. O D. Dollars per week. What is the regression's predicted eamings for a 45-year-old worker? The regression's predicted eamings for a 45-year-old worker are S (Round your response to two decimal places.) Will the regression give reliable predictions for a 76-year-old worker? O A. No, the oldest worker in the sample is 65 years old; 76 years is far outside the range of the sample data. O B. Yes, although the oldest worker in the sample data is 65 years old, the model is developed to make forecasts and predictions for workers younger than 25 years of age and older than 65 years of age Given what you know about the distribution of earnings, do you think it is plausible that the distribution errors in the regression is normal? O A. No, the distribution of earnings is positively skewed and has kurtosis larger than the nomal. O B. Yes, the distribution of eamings is symmetric and thus nomal. OC. No, the distribution of earnings is negatively skewed and has kurtosis smaller than the nomal. The average age in this sample is 38.7 years. What is the average value of AWE in the sample? The sample mean of AWE is $- (Round your response to two decimal places.)
