Transcribed Image Text:Preliminary analyses indicate that you can consider the assumptions for using nonpooled
t-procedures satisfied. Researchers obtained the following data on the number of acute
postoperative days in the hospital using the dynamic and static systems. Obtain a 90% confidence
interval for the difference, μ₁ −μ₂, between the mean numbers of acute postoperative days in the
hospital with the dynamic and static systems. (Note: x₁ = 7.42, s₁ = 1.38, x₂ = 11.67, and s2 = 4.68)
The 90% confidence interval is from to
(Round to three decimal places as needed.)
