the right one. Healthcare professionals must deal with these challenges based on their training and knowledge of ethical principles and decision making. Choose an ethical dilemma from the list below and answer the questions that follow. Use your knowledge and understanding from what you have already learned from Unit 1 and 2 lessons and the textbook reading assignments. Genetic testing and home test kits Physician-assisted death Artificial intelligence and clinical decision making Organ transplantation and artificial organs Note: If you would like to choose a dilemma other than one on the list, please consult with your instructor and obtain permission. Describe the issue and why and how it poses an ethical dilemma for healthcare providers and healthcare organizations? What ethical principle(s) would be applicable to the dilemma? Describe the ethical decision-making steps used to come to an ethical decision? With whom would a healthcare professional consult in coming to a decision? How are your personal values challenged? What would be a personal bias or conflict of interest in resolving this dilemma

2,3,4,7). If it lands tails, a fair six-sided die is thrown (with values 3,4,5,6,7,9). Regardless of which die is used, Alice eats n grains of rice, where n is the largest prime factor of the die result (for example, the largest prime factor of 9 is 3). (a) What is the conditional probability that the coin lands heads, given that Alice eats three grains of rice? (b) Suppose that the entire experiment is conducted twice on the following day (starting with a new coin toss on the second run-through). What is the conditional probability that the coin lands heads on both run-throughs, given that Alice eats a total of five grains of rice during the two run-throughs? (Do not count the two grains from part (a) in part (b); we assume two brand new experiments, each with a new coin toss. Start your solution by defining a suitable partition of the sample space. Please use an appropriate notation and/or justification in words, for each value that you give as part of your solution.) Exercise 5) Alice and Bob throw an unfair coin repeatedly, with probability 2/5 of landing heads. Alice starts with £2 and Bob starts with £3 . Each time the unfair coin lands heads, Alice gives Bob £1 . Each time the unfair coin lands tails, Bob gives Alice £1 . The game ends when one player has £5 . (a) Draw a labelled Markov chain describing the problem, and write down a transition matrix P. Write down the communication classes, and classify them as either recurrent or transient. (b) Using the transition matrix, calculate the probability that Alice loses all of her money in exactly four tosses of the unfair coin. (c) Calculate the (total) probability that Alice loses all of her money (before Bob loses all of his). (d) Calculate the expected (mean) number of tosses of the unfair coin, for the game to end.

audience. This assignment will focus on how criteria can change and how you need to tailor your essay to these changing audiences. In good times, people may want homes with soaring entryways, lots of space and premium appliances. In tougher times, they may care more about efficient use of space, quality insulation, and energy efficient appliances. When gas prices are low, people love to buy SUVs and trucks, but when gas prices get higher, they prefer hybrid cars with good fuel efficiency. Think of two scenarios, much like the ones above, where different audiences or different times create different criteria for evaluation. For example, what impact might global warming have on the way we determine desirable places to live or vacation? How might a changing economy change the way we view successful careers? If people across the globe continue to put on weight, how might standards of beauty change? Si i have this assignment for English I just don't understand it here is the assignment: Explore two scenarios in which change might revise customary values and standards for evaluation. Each scenario should be a paragraph of at least 100 words in length.

de by credit card; you think this is true at your store as well. On a typical day you make 20 sales. Show that this situation can be modeled by a binomial distribution. For credit, you must discuss each of the criteria required for a binomial experiment. Define the random variable x in this scenario, using the context of the problem. List all possible values of x for this situation. On one trial for this scenario, what does “success” mean? Explain using the words of the problem. What is the probability of success in this scenario? What is the probability of failure in this scenario? Probability Distribution Instructions¬¬¬¬ In Excel, create a probability distribution for this scenario. Label Column A as “x” and Column B as “P(x).” In Column A, list the numbers 0 to 15. In Column B, use BINOM.DIST.RANGE to calculate the probability for each x value. Highlight the probability cells, then right click and select Format Cells. Format the probability cells as “Number” and have Excel show 4 decimal places. Create a probability histogram using the probabilities you calculated. Format and label it properly. Be sure to use the “Select Data” button to change the x-axis so it correctly lists the x-values.
