STAT homework : mathematics expert
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.
| Group 1 | Group 2 |

| 46 | 71 |
| 60 | 55 |
| 55 | 67 |

| N1= | N2= |
| Mean1 | Mean2 |
Sum of Scores Squared | For Group 1 = | For Group 2 = |
| Variance1= | Variance2 = |
| S1 | S2 |

- Remember that the standard form for the quadratic function equation is y = f (x) = ax2 + bx + c and the vertex form is y = f (x) = a(x – h)2 + k, where (h, k) are the coordinates of the vertex of this quadratic function’s graph.
