Use the following sample information to construct a 90% confidence interval for the difference in the two population means. What is the upper value of the interval?

(Round your answer to 2 decimal places, e.g. 1.75.)

Sample 1:

n₁ = 33 ; mean x₁ = 70.1 , ₁ =6.23

Sample 2:

n₂= 32 ; mean x₂= 68.3 ; ₂ =7.4
