Yes
(d-1) Find the 95% confidence interval for slope.(Round your answer to 4 decimal places.)
Confidence interval is from Not attemptedto Not attempted.
(d-2) The confidence interval does not contain zero, which implies
there is a relationship between the total assets (billions) and total revenue (billions).
