The formula for the margin of error E for a c% confidence interval for the slope can be written as E = tc(SE Coef). The Minitab display is based on n = 17 data pairs. Find the critical value tc for a 99% confidence interval in the relevant table. Then find a 99% confidence interval for the population slope . (Use 3 decimal places.) tc lower limit upper limit Please show steps. Also, not quite sure about d.f. , I think it should be n-1 = 16. When I look in the t table, I'm not coming up with the right tsubc value. Should the E value + - from 0 ? Not sure about that
