Toy Assembly Test 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 a = 0.05, can it be concluded that learning took place? Use the P-value method. Assume that all variables are normally or approximately normally distributed. Let µ, be the trial 1 average and 4p = 41-H2. Child 1 2 3 4 5 6 7 Trial 1 100 150 150 110 130 120 118 Trial 2 93 130 150 90 105 110 120 Send data to Excel

Toy Assembly Test 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 a = 0.05, can it be concluded that learning took place? Use the P-value method. Assume that
all variables are normally or approximately normally distributed. Let µ, be the trial 1 average and u, = 41-42.
