Find an article about the misuse of statistics and share what you have learned from the article. Then, find an example of when statistics were misused/skewed and state the reason why you think the statistics were reported that way.

Question 1: Consider the linear block cipher with block length n and alphabet {0, 1}. On the key space of matrices A ∈ {0, 1} (n,n) with det(A) ≡ 1 (mod 2), choose the uniform distribution. Show that this cryptosystem does not have perfect secrecy. (Use the definition of perfect secrecy, and find a counterexample with n = 2, for instance.) 2: Let n be a positive integer. A Latin square of order n is an n × n array L of the integers 1, 2, . . . , n such that every one of the n integers occurs exactly once in each row and each column of L. An example of a Latin square of order 3 is as follows:  1 2 3 3 1 2 2 3 1  . Given any Latin square L of order n, we can define the following cryptosystem: Take P = C = K = {1, 2, . . . , n}. For 1 ≤ i ≤ n, the encryption function Ei is defined to be Ei (j) = L(i, j). (Hence each row of L gives rise to one encryption function.) Give a complete proof that this Latin square cryptosystem achieves perfect secrecy. (Use Shannon’s theorem).If the question descriptions not clear enough, please check the picture file I posted.

Instructions:Your initial post will include five screen shots and four sentences (one sentence for each of the last four screen shots).Screenshot #1Flip a coin. Your flip will determine the trigonometric function you will be working with for your initial post.Heads = use sineTails = use cosineFor example, if I flipped a tail, my initial post would focus on the trigonometric function cosine.Graph your function and take a screen shot of the graph.You can use any program you like. Here is one option: Illuminations: Trigonometric Graphing.Please refer to the discussion board on how to take screen shots.Graph  y=cos(x) ory=sin(x) Your subject line will be cos(x) or sin(x) depending on your flip.Screenshot #2Now, consider this equation. The equation used will depend on your original coin toss.y=Acos(B(x−C))+D y=Asin(B(x−C))+DUsing the Illuminations: Trigonometric Graphing site, figure out what happens when you make A larger (try 1, 2, 3, and 4).Explain in one sentence what happens as you make A larger and tell us what this transformation is called.Then pick an interesting large number (something larger than 1), and graph y=Acos(x)  or  y=Asin(x)The equation used will depend on your original coin toss.Take a screen shot of your graph and post the equation.Screenshot #3Using the Illuminations: Trigonometric Graphing site, figure out what happens when you make B larger (try 1, 2, 3, and 4) and tell us what this transformation is called.Explain in one sentence what happens as you make B larger.Then pick an interesting large number (something larger than 1), and graph y=cos(Bx)  or  y=sin(Bx)The equation used will depend on your original coin toss.Take a screen shot of your graph and post the equation.Screenshot #4Using the Illuminations: Trigonometric Graphing site, figure out what happens when you make C larger (try 0, 30 degrees, 45 degrees, and 60 degrees) and tell us what this transformation is called.Explain in one sentence what happens as you make C larger.Then pick an interesting large number (something larger than 0), and graph y=cos(x+C) y=sin(x+C)The equation used will depend on your original coin toss.Take a screen shot of your graph and post the equation.Screenshot #5Using the Illuminations: Trigonometric Graphing site, figure out what happens when you make D larger (try 0, 1, 2, and 3) and tell us what this transformation is called.Explain in one sentence what happens as you make D largerThen pick an interesting large number (something larger than 0), and graph y=cos(x)+D or y=sin(x)+DThe equation used will depend on your original coin toss.Take a screen shot of your graph and post the equation.Response Post:Pick another student’s post who flipped their coin opposite of you.For my example, I would pick someone who flipped heads, or has sin(x) in their subject line.Review the other student’s post.Does each of their answers make sense to you?Explain in at least two sentences why or why not their post makes sense.Please be respectful of other students’ work.Pick two of their transformations (meaning A, B, C, or D and the corresponding graph).What happens when you change the transformation from a positive value to a negative value? For example, if you picked A and D, what happens when you change equations to: y=−Acos(x)  or y=−Asin(x)Remember, find the Trig function opposite of yours.What happens when you change the equation to: y=cos(x)−D  or y=sin(x)−DPost a screen shot of both transformations together: y=−Acos(x)−D  or  y=−Asin(x)−D
