An educational researcher devised a wooden toy assembly project to test learning in 6 year olds.  The time in seconds to assemble the toy assembly was noted, and the toy was disassembled out of the child's sight. Then the child was given the task to repeat. The researcher would conclude that learning occurred if the mean of the second assembly times was shorter than the first assembly times.  At a = 0.01, can it be concluded that learning took place?
