Transcribed Image Text:2. Neuroscience researchers examined the impact of
environment on rat development. Rats were randomly
assigned to be raised in one of the four following test
conditions: Impoverished (wire mesh cage - housed alone),
standard (cage with other rats), enriched (cage with other
rats and toys), super enriched (cage with rats and toys
changes on a periodic basis). After two months, the rats
were tested on a variety of learning measures (including the
number of trials to learn a maze to a three perfect trial
criteria), and several neurological measure (overall cortical
weight, degree of dendritic branching, etc.). The data for
the maze task is below. Compute the appropriate test for the
data provided below.
