Part 1What is the expected value of a single lottery ticket?______ dollars (Round to the nearest cent as needed.)Part 2If you spend $365 per year on the lottery, how much can you expect to win? ______ dollars (Round to the nearest cent as needed.)17. In the game of roulette, when a player gives the casino $13 for a bet on the number 18, the player has a 37/38 probability of losing $13 and a 1/38 probability of making a net gain of $455. (The prize is $468, but the player’s$13 bet is not returned, so the net gain is $455.) If a player bets $13 that the outcome is an odd number, the probability of losing $13 is 20/38 and the probability of making a net gain of $13 is 18/38. (If a player bets $13 on an odd number and wins, the player is given $26 that includes the bet, so the net gain is $13.) Complete parts(a) through(c) below a. If a player bets $ 13 on the number 18, what is the player’s expected value? The expected value is_____ dollars. (Round to the nearest cent as needed.)b. If a player bets 3$that the outcome is an odd number, what is the player’s expected value? The expected value is negative _____ dollars.(Round to the nearest cent as needed.)
c. Is the best option to bet on 25, to bet on odd, or not to bet? Why? A. Betting on 25 is best because it has the highest potential net gain. B. Not betting is best because it has the highest expected value. C. Betting on odd is best because it has the highest expected value. D. Betting on odd and not betting are equally good because their expected values are higher than the expected value of betting on. 18. An MP3 player is loaded with 50 musical selections: 30rock selections, 8 jazz selections, and 12 blues selections.

Use the attached data set for our company to address the following.

Task assignments to employees are supposed to be done at random. On a certain day, all the best jobs, in order of desirability, were given to the men. Is there evidence of sex discrimination? Discuss this also in the context of a continuing, daily operation. What would happen if you tested the randomness hypothesis everyday?

Chi-Square Data Analysis

Chi-Square Data Analysis

Prior to beginning work on this assignment, review Chapter 10 in your course textbook, pages 109 to 120 in Chapter 7 of the Jarman e-book, and the Week 2 Instructor Guidance. Also, review The Chi-Square Test: Often Used and More Often Misinterpreted and The Chi-Square Test of Independence articles Also, review the Two-Way Tables, Chi-Square: Lecture 11, Chi-Square Tests: Crash Course Statistics #29 (Links to an external site.), and Chi-Square Test for Association (Independence) | AP Statistics | Khan Academy (Links to an external site.) videos; and review the How to Chi-Square Test (Links to an external site.) and How to Interpret Chi-Squared (Links to an external site.) web articles. Also, complete the Week 2 learning activity and Week 2 weekly review.

.For the calculations in this assignment, you may use either Excel or the free VassarStats: Website for Statistical Computation (Links to an external site.) program online. Instructions for performing a chi-square test of independence in Excel are included in Section 10.4 of the textbook, accompanied by a screencast demonstrating the process in the electronic version. For this test, you may prefer VassarStats (Links to an external site.) because it is more automated than Excel. You also have the option of calculating the chi-square manually but if you choose this option, you must show your work and explain all of the steps taken to solve for the chi-square value and to determine statistical significance.

In your paper, begin with a paragraph introducing the scenario and explaining why a chi-square test is needed for the situation. Then, address the following:

Identify which chi-square test you used and which program or procedure you used for the analysis.
Describe the procedure you used to calculate the chi-square.
If using VassarStats (Links to an external site.), copy and paste the data entry area and output into your paper. If using Excel, submit the Excel spreadsheet separately and mention in your paper that the spreadsheet is attached. If using hand calculations, include a table showing the observed and expected frequencies, along with the row and column totals and chi-square calculations.
Report the chi-square value, degrees of freedom, and the p
Explain how you determined the p Is the result statistically significant?
If the test is a chi-square test of independence with a statistically significant result, report the effect size using Cramér’s V.
Explain the meaning of the results in terms of the scenario.
Discuss any assumptions, limitations, and implications associated with the situation and analysis.
Summarize the main points of the paper in a concluding paragraph.
The Chi-Square Data Analysis paper

Must be two to three double-spaced pages in length (not including title and references pages) and formatted according to APA Style as outlined in the Writing Center’s APA Style (Links to an external site.) resource.

Optimization Using Healthcare Examples

In what other ways might optimization be used to maximize healthcare delivery? What types of processes and workflows are best served by optimization in health services organizations?

Optimization is a vital prescriiptive analytic technique that healthcare administrators can use to help address challenges in effective and efficient healthcare delivery. Health decision makers may seek to find optimal solutions for a particular objective given various constraints. For example, optimization is often used for generating nursing staff schedules to ensure appropriate staff coverage with varying patient inflows.

For this Assignment, you will be using optimization techniques to evaluate two separate medical problems, one involving mechanical heart valves and another involving a pharmaceutical company. Review the resources for this week, and examine the different optimization techniques that can be used for this Assignment.

Complete Problem 36 on page 657 (mechanical heart valves) and Problem 42 on page 659 (pharmaceutical company) of your course text.
Create a embedded Excel analysis as a Microsoft Word management report.
