Two different sprays for rewaterproofing parkas are compared by treating 5 parkas with spray 1 and 6 with spray 2. After one day, each parka is sprayed with water and the parka is rated on its ability to repel water. The following conclusion is reported "Under the assumption of normal populations with equal but unknown standard deviations, the 90% confidence interval for u1-u2 is (3.6,5.2)." From this report, State the conclusion of testing Ho: u1-u2=4.1 versus H1: u1-u2 (does not equal) 4.1 at a=.10?
