A detailed description of the variables used in the dataset is available here ¹. Use a statistical package of your choice to answer the following questions. What is the median value of height in the sample? The median value of height in the sample is (Round your response to two decimal places) Estimate average earnings for workers whose height is at most 67 inches. Average earnings for workers whose height is at most 67 inches is estimated to be $ (Round your response to two decimal places) Estimate average earnings for workers whose height is greater than 67 inches. Average earnings for workers whose height is greater than 67 inches is estimated to be $ (Round your response to two decimal places) On average, how much more (in absolute value) do taller workers earn compared to shorter workers? Taller workers earn $ OA. Because the variable Height is continuous. OB. Because the variable Earnings is discrete. OC. Because the variable Height is discrete. O D. Because the variable Earnings is continuous. Run a regression of Earnings on Height. Construct a 95% confidence interval for the absolute value of the difference in average earnings? The 95% confidence interval for the difference in average earnings is $[ (Round your response to two decimal places) Consider the following scatterplot of annual earnings (Earnings) on height (Height). Why do the points on the plot fall along horizontal lines? Earnings 85960- 75960- 65960- 55960- 45960- 35960 25960- more than shorter workers on average.
