Complete the following Stata operation with data Earnings_and_Height.dta: 1. Describe the variable earnings at height less than or equal to 67 inches and at height greater than 67 inches. Draw the frequency distribution of the two cases. 2. Calculate the difference of earnings in the above two cases, save as a scalar difference. 3. Use the scatter command to draw with earnings as the Y axis, height as the X axis, and "income" as the Y axis name, "height" as the X axis name. 4. Using hours as the dependent variable and height as the independent variable, we estimated the wages of 67, 70, and 65 inches, respectively.
