1. Answer A-E using the Stata regression output attached in Table 1
   1. Conduct a 2-sided 5-step significance test of the slope, showing how to calculate t using the formula in the textbook and finding p in Table B. Use alpha = .05.
   2. Report t and p for the significance test from the Stata output.
   3. Report and interpret the 95% confidence interval for the slope from the Stata output.
   4. Construct the 95% confidence interval for the slope using the formula in the textbook.
   5. Show how you can calculate r2 using the sum of squares measures reported in the Stata output.
