An educational researcher devised a wooden toy assembly project to test learning in 6-year-olds. The time in seconds to assemble the project 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 less than the mean of the first assembly times. At α = 0.01, can it be concluded that learning took place? Use the P-value method, and find the 99% confidence interval of the difference in means.
