Assignment: Hypothesis Testing

INTRODUCTION TO HYPOTHESIS TESTING

For the third component of the Session Long Project, write a (2-3 pages) paper in which you:

1. Develop a null hypothesis and an alternative hypothesis based on the data you have collected.
2. Discuss why you have chosen the hypotheses you developed above. Be sure to discuss the concept of null hypothesis in your response.

SLP Assignment Expectations

Assessment and Grading: Your paper will be assessed based on the performance assessment rubric that is linked within the course. Review it before you begin working on the assignment.

Mitosis, Meiosis, and Fertilization All cells in your body, except the sperm and egg, have 46 chromosomes arranged in 23 pairs. These cells reproduce through a process called mitosis.During mitosis, the cell’s nucleus—including the chromosomes—duplicates itself and the cell divides. Two new cells are formed, each containing the same DNA as the original cell, arranged in the same 23 pairs of chromosomes. However, a different type of cell division—meiosis—forms eggs and sperm (which also are called gametes). During meiosis, a cell of the testes (in men) or ovaries (in women) duplicates its chromosomes but then divides twice, thus forming four cells, each of which has only half of the genetic material of the parent cell (Johnson, 2017). By the end of meiosis, each egg or sperm has 23 unpaired chromosomes. During fertilization, an egg and a sperm fuse to create a single cell, called a zygote. In the zygote, the 23 unpaired chromosomes from the egg and the 23 unpaired chromosomes from the sperm combine to form one set of 23 paired chromosomes—one chromosome of each pair from the mother’s egg and the other from the father’s sperm. In this manner, each parent contributes half of the offspring’s genetic material. Page 41

Figure 3 shows 23 paired chromosomes of a male and a female. The members of each pair of chromosomes are both similar and different: Each chromosome in the pair contains varying forms of the same genes, at the same location on the chromosome. A gene that influences hair color, for example, is located on both members of one pair of chromosomes, at the same location on each. However, one of those chromosomes might
