The Central Limit Theorem states that, given a sufficient sample size, the shape of the distribution of sampling means for any data set will be a ______________ curve.
You run an experiment to see if first graders with Autism report different levels of school enjoyment than their peers. You create a school enjoyment scale (1-10, 10 = Really, really enjoys school). Your first graders with Autism have a mean value of 4.56. Your control group of first graders report a mean of 8.00 with a standard deviation of 3.21. Calculate the z-score that will allow you to test your hypothesis, rounded out two decimal places
