If we use the sample data in Exercise 2, we get this 95% confidence interval estimate: 1.0

Question:

If we use the sample data in Exercise 2, we get this 95% confidence interval estimate: 1.0 mi/gal < µd< 3.8 mi/gal. Treating the same data as independent samples yields —7.8 mi/gal < µ1 - µ2< 12.6 mi/gal for a 95% confidence level.
What is the difference between interpretations of these two confidence intervals?
