INTRODUCTION TO NORMAL DISTRIBUTIONS
The normal distribution is the most important and most widely used distribution in statistics. It is sometimes called the "bell curve," although the tonal qualities of such a bell would be less than pleasing. It is also called the "Gaussian curve" after the mathematician Karl Friedrich Gauss. As you will see in the section on the history of the normal distribution, although Gauss played an important role in its history, Abraham de Moivre first...

...A. Genetics
Ribosomal 5S RNA can be presented as a sequence of 120 nucleotides. Each nucleotide can be represented by one of four characters: A (Adenine), G (Guanine), C (Cytosine), or U (Uracil). The characters occur with different probabilities for each person. We wish to test if a new sequence is the same as ribosomal 5S RNA. For this purpose, we replicate the new sequence 100 times and find that there are 60 A’s in the20th position. Use a 0.05 level of significance.

1.) Factor
100x^2 – 49
to factor, use the difference of squares formula, because both the terms are perfect squares
the difference of squares formula is a^2 – b^2 = (a-b)(a+b)
therefore
100x^2 – 49 = (10x)^2 – 7^2 = (10x – 7)(10x +7)
(5 pts)
2.) Solve
x^2 – 11x = -30
(x^2 – 11x) + 30 = -30 +30

...BIOSTATISTICS
* Effect modification: effect of the main exposure on the outcome is affected by another variable. It is NOT a bias!
* Case-control study: also known as retrospective study. Divided into “cases” and “controls.” If disease is rare, the odds ratio will approximate the relative risk (following subjects over time.)
* Cohort study (Retrospective or prospective): divided into “exposed” and “non-exposed.” Study subjects are free of the outcome at the...
