Problem #1

You ask your graduate student to roll a die 5000 times and record the results.

a)     Give the expected mean and standard deviation of the outcome.

P= 1/6 , Q= 5/6

NP= 5,000

NP X P= 5,000 *1/6 =

5,000/6

SD: Square root(5,000 * 1/6 * 5/6) = Square Root

b) The die roll experiment is repeated (though with a different graduate student – for some reason your previous student went to work with a different advisor). However in this case, the die is weighted so that a 6 shows up 11% of the time, a 1 shows up 21% of the time, and all remaining numbers show up 68% of the time (17% each). Now what is the expected mean and sd of 5000 rolls?

Problem #2

Part a: A product manager is evaluating production and inventory. In looking over the data, she decides that a product should be continued if it sold 23,000 over the previous year. In addition, the product is considered “popular” if it receives 50 mentions by the local press over the past year.

In selecting a product at random from the catalog, let C be the likelihood that this particular product sold 23,000 products the past year. Let P be the likelihood that the product received the 50 or more mentions by the local press.

The analyst determines that P(C) = 0.297, P(P) = 0.162, and the probability that a product has sold 8000 items, and was ‘popular’ is 0.083. What is the probability that a randomly selected product either sold the requisite 23,000 items, or that it is ‘popular’?

Part b: Where would the analyst have come up with the probaility values for P(C) andP(P)?

Problem #3

You are playing a game of backgammon, and realize that if either of the two dice on your next roll is a 4, you will win the game. (It’s also fine for both dice to be a 4, but you only need one). However, if you don’t get a 4 on either die, your opponent will win on their next move.

Just to restate: As long as you see a 4 on either of the dice, you will win, otherwise you lose. What is the probability that you will win the game?

Problem #4

You are a coach of a basketball team, and the final game of the season is on the line. Here are the current season’s data for your two best shooters, Lisa and Maggie. The {0, 1, 2, 3} represents the number of baskets they made out of the 3 throws. For example, Lisa makes all 3 baskets 10% of the time, and makes 0 (ie misses all 3) 16% of the time.

a)     You must pick one of the following two players to make 3 free-throw attempts. Which one is most likely to give you your best result? Be sure to explain why.

b)      Suppose you needed to make all 3 baskets in order to win, otherwise you would lose. Who would you pick? B

I need assistance on what I am doing wrong, I've been trying to declare "getRandomLetter" as a scope, but haven't found how to all day. It's been about 3+ hours and I still have nothing. Please help fix these and let me know what I am doing wrong (There may be more simple ways of coding all this, but I just need help fixing the errors with current code, thank you). I am trying to have buildAcronym() hold the position of going from A-Z , & as well as getRandomLetter() choose a letter from A-Z using the ASCII character set. This is a bit of the prompt where it asks to set these up. If I am off, I do apologize.

Define and overload two void-typed functions named buildAcronym that assign a (pseudo)-random uppercase letter to two (2) or three (3) character parameters, depending on the version called. Each character in an acronym must be a unique uppercase letter. Two arguments (or three, depending on the version called) will be assigned a random character literal, which can then be printed out in main.

These are my errors.

An October 25, 2012 article in the New England Journal of Medicine reports the results of a study examining aspirin and survival among patients with colorectal cancer. The following pieces of text are taken directly from the article abstract: (my edits are in italics) “METHODS We obtained data on 964 patients with rectal or colon cancer from the Nurses’ Health Study and the Health Professionals Follow-up Study, including data on aspirin use after diagnosis and the presence or absence of PIK3CA mutation…… RESULTS Among patients with mutated-PIK3CA colorectal cancers, regular use of aspirin after diagnosis was associated with superior colorectal cancer–specific survival (adjusted relative risk for cancer-related death, 0.18; 95% confidence interval [CI], 0.06 to 0.61; P<0.001 by the log-rank test) and overall survival (adjusted relative risk for death from any cause, 0.54; 95% CI, 0.31 to 0.94; P = 0.01 by the log-rank test). In contrast, among patients with wild-type PIK3CA, regular use of aspirin after diagnosis was not associated with colorectal cancer–specific survival (adjusted relative risk, 0.96; 95% CI, 0.69 to 1.32; P = 0.76 by the log-rank test) ) or overall survival (adjusted relative risk, 0.94; 95% CI, 0.75 to 1.17; P = 0.96 by the log-rank test)” The authors present the following graphic as part of the article: (on the next page) Statistical Reasoning in Public Health 1, 2016: Ho

1. What is the outcome of interest for this study?

2. What is the primary predictor of interest for this study?

3. What type of study design is this?

4. Describe the findings with regards to aspirin and survival in patients with colorectal cancer with respect to the presence or absence of the PIK3CA mutation.

5. Even though the authors estimated the association between aspirin and survival separately for the mutated-PIK3CA and wild-type PIK3CA, each of the two associations was adjusted for multiple factors including age, sex, year of diagnosis etc… Why was it potentially necessary to do this adjustment?

You will design and implement a graphics program that draws four concentric rectangles in a window, using four different colors of your choice, meeting the following specifications.

• The size of the window is determined by the user of the program. To be specific, you should prompt the user for both the width and height of the window (in pixels), and then you should set the size of the window using these values. (Hint: use the setup() method of the window.) Make the largest colored rectangle by setting the background color of the window. The three other colored rectangles will be drawn using the draw_rectangle() function described below in Program Design.

• After the first rectangle, the size of each rectangle will be half of the size of the one before it. Using the rectangles shown in the graphic as an example, the length and width of the red rectangle are half of the length and width of the blue rectangle, respectively. Then the length and width of the yellow rectangle are half of the length and width of the red rectangle, respectively, etc.

• You should use a for loop to draw the three rectangles. Because of this, only one line of code in your program should have a call to the function draw_rectangle().

• Use meaningful variable names.

• Use horizontal and vertical white space reasonably and consistently.

• Use named constants as appropriate.

Program Design Your program is to be implemented using the function draw_rectangle(), which draws a rectangle centered in the window of a specified size and color. In order to do this, start your program with exactly the following lines of codes: import turtle import sys sys.setExecutionLimit(60000) # 60 seconds def draw_rectangle(turt, width, height, color): turt.pencolor(color) turt.fillcolor(color) turt.up() x = - width / 2 y = height / 2 turt.goto(x,y) turt.down() turt.begin_fill() # Draw the top turt.setheading(0) turt.forward(width) # Draw the right side turt.right(90) turt.forward(height) # Draw the bottom turt.right(90) turt.forward(width) # Draw the left side turt.right(90) turt.forward(height) turt.end_fill() # Your code goes here

Mendoza is considering investing in IBM. However he is captivated by IBM's growth. IBM had made a remarkeable change from a strugling company to a leading company in the personal computer market. Mendoza has asked for your advice as to whether or not the growth is genuine. He suspects there might have been some fraudulent or unethical actions taken by IBM to increase its income. After a rief look at the recent history and performance of IBM, you decide to look more closely at the financial statements. As you review the financial statements, you begin to have some concerns about the nature of IBM's growth. Certain accounting procedures cause you to have doubt as to whether the growth came from IBM's core business operations or from carefully planned accounting adjustments that seem to be unethical. As you proceed in your investigations, you pay particular attention to the following areas. Pensions IBM changed its pension plan to a cash balance plan. The returns of this plan exceeded the amount recognized as an expense. Accounting rules require the company to add the excess returns to earnings but the gains cannot be spent on anything other than pension benefits. IBM increased its earnings per share by making this adjustment. Stock repurchases since 1995, IBM has spent a lot of money making stock repurchases. A stock repurchase may be beneficial to a company by increasing earnings per share since there ill be fewer share holders across which to spread the earnings. You conclude that the financial statements were in accordance with generally accepted accounting principles (GAAP) and you are confident that all accounting rules were followed. However, you have to explain to Mendoza whether the behavior was ehtical. What wiould you tell him?
