A group of researchers studied functional impairment scores in a group of 10 patients before and after a new rehabilitation intervention. The researchers set the alpha at 0.05 which meant that the critical t value would be 2.26 (9 df). Data analysis showed t(9)=2.84, p=.045. What do these results mean
