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.
