2)  Suppose an educator is interested in the difference in math achievement of third=grade students who are taught under two conditions.  The first condition is a highly structured environment in which a fixed time is given for the teaching and learning of math concepts.  The second condition is a less structured environment in which the same concepts are presented but with n o set time for completion of the teaching-learning process.  We will call the group assigned to the highly structured environment group 1 and the group assigned to the less structured environment group 2.  At the end of the six weeks, a random sample of each group of students takes an achievement test.  The level of significance is .05.  The educator tells us to conduct a negative directional test.

a.  Find the cv.

b.  Find the test statistic.

c.  Intepret the results.

I have helped you by identifying some key data points you must find above before you finish the research for the educator.
