Exercise 18
Please respond to the following questions in Microsoft Word. See attachment bellow with lecture. 1. Mayland et al. (2014) do not provide the degrees of freedom ( df ) in their study. Use the degrees of freedom formulas provided at the beginning of this exercise to calculate the group df and the error df . 2. What is the F value and p value for spiritual need—patient? What do these results mean? 3. What is the post hoc result for facilities for the hospital with LCP vs. the hospital without LCP (see Table 2 )? Is this result statistically significant? In your opinion, is this an expected finding? 4. What are the assumptions for use of ANOVA? 5. What variable on Table 3 has the result F = 10.6, p < 0.0001? What does the result mean? 6. ANOVA was used for analysis by Mayland et al. (2014) . Would t -tests have also been appropriate? Provide a rationale for your answer. 7. What type of post hoc analysis was performed? Is the post hoc analysis performed more or less conservative than the Scheffé test? 8. State the null hypothesis for care for the three study groups (see Table 2 ). Should the null hypothesis be accepted or rejected? Provide a rationale for your answer. 9. What are the post hoc results for care? Which results are statistically significant? What do the results mean? 10. In your opinion, do the study findings presented in Tables 2 and 3 have implications for end of life care? Provide a rationale for your answer.

MC Discrete Probability Distribution Expected Value & Development Analysts Worksheet
EXPERIENCE 4 ASSIGNMENT Creating a discrete probability distribution: A venture capitalist, willing to invest $1,000,000, has three investments to choose from. The first investment, a social media company, has a 20% chance of returning $7,000,000 profit, a 30% chance of returning no profit, and a 50% chance of losing the million dollars. The second company, an advertising firm has a 10% chance of returning $3,000,000 profit, a 60% chance of returning a $2,000,000 profit, and a 30% chance of losing the million dollars. The third company, a chemical company has a 40% chance of returning $3,000,000 profit, a 50% chance of no profit, and a 10% chance of losing the million dollars. a. Construct a Probability Distribution for each investment. This should be 3 separate tables (See the instructors video for how this is done) In your table the X column is the net amount of profit/loss for the venture capitalist and the P(X) column uses the decimal form of the likelihoods given above. b. Find the expected value for each investment. c. Which investment has the highest expected return? d. Which is the safest investment and why? e. Which is the riskiest investment and why? When you are finished with your Assignment, upload the completed file below. You can create a spreadsheet with all of the above and submit it or create a document or write it up by hand and scan it.Suppose you work for a company that manufactures electronics. The development analysts estimate that 1% of their flagship product will fail within 2 years of the purchase date, with a replacement cost of $ 1500. A newly hired associate at the company proposes to charge $ 6 for a 2-year warranty. a. Compute the expected value of this proposal. Let X be the amount profited or lost (by the company) on the warranties and P(X) is the probability. E=E= b. Interpret the expected value in complete sentences. (See Example 4.3 in the textbook for an example of this) c. Write your review of the proposal and address it to VP of marketing and promotions. Include the following in your essay: Would the proposal benefit the company? Why or why not? Include the new proposed cost, new expected value, interpretation of the new expected value, and explanation of how the new cost was chosen. Question 1Choose FileNo file chosen PRACTICE E4 A group of people were asked if they had run a red light in the last year. 458 responded "yes", and 423 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year. Give your answer as a fraction or decimal to 4 decimal places A random variable is defined as a process or variable with a numerical outcome. Which of the following are random variables?For families with 5 children, let XX be the number of children with Genetic Condition B. Can the following table be a probability distribution for the random variable XX?Assume that 12 jurors are randomly selected from a population in which 80% of the people are Mexican-Americans. Refer to the probability distribution table below and find the indicated probabilities. The amount of rain, in inches, that will fall next Friday in Dallas, TX.
