A psychologist wanted to know whether there were visual spatial differences in the
development of children if they are raised within a hunter-gather culture. A sample of n=36
children between the ages of 6 - 8 years old were recruited and a cognitive test scores 145 .
The general mu =120 with a population standard deviation of 16 . Assuming that the
researcher is using a two-tailed test with alpha =.05, what decision should be made? Include
your z calculation. State the 3-process statement for step 4.
