User generated content is uploaded by users for the purposes of learning and should be used following Studypool's honor code & terms of service.
Explanation & Answer
P(x=4 | mean =1.8) = e-1.8 (1.8)4/4! = 0.072302
alternatively
=poisson(4,1.8,false) or
=poisson(4,1.8,0)
= 0.072302

MATH 225N Chamberlain College of Nursing Week 4 Probability Discussion
Probability plays a major role in the medical community. Diagnoses are based on probabilities. They are really questions or "what if's", and are answered by the probability that the treatment will be the best for the ailment.
Let's look at probability in terms of both the real world and the medical community.
Survey 30 people to find out if they are left-handed or right-handed, and use the following chart to create a contingency table with the information.
Left handed Right handed Total Female Male Total
Answer the following questions about the information in your contingency table:
If a person is randomly selected from the survey participants, what is the probability that the person will be left-handed?
If you randomly choose a female from the people you surveyed, what is the probability that she is left-handed?
What is the odds ratio of choosing a left-handed female?
What is the relative risk of choosing a left-handed female?

Anthem College Phoenix Statistics and Anova Worksheet
Question 80 A
pharmaceutical company produces the drug NasaMist from four chemicals.
Today, the company must produce 1000 pounds of the drug. The three
active ingredients in NasaMist are A, B, and C. By weight, at least 8%
of NasaMist must consist of A, at least 4% of B, and at least 2% of C.
The cost per pound of each chemical and the amount of each active
ingredient in one pound of each chemical are given in the file
P14_80.xlsx. It is necessary that at least 100 pounds of chemical 2 and
at least 450 pounds of chemical 3 be used. Determine the cheapest way of producing today’s batch of NasaMist.Use
SolverTable to see how much the percentage of requirement of A is
really costing the company. Let the percentage required vary from 6% to
12%.q86The government is auctioning off oil
leases at two sites: 1 and 2. At each site 10,000 acres of land are to
be auctioned. Cliff Ewing, Blake Barnes, and Alexis Pickens are bidding
for the oil. Government rules state that no bidder can receive more than
40% of the land being auctioned. Cliff has bid $10,000 per acre for
site 1 land and $20,000 per acre for site 2 land. Blake has bid $9000
per acre for site 1 land and $22,000 per acre for site 2 land. Alexis
has bid $11,000 per acre for site 1 land and $19,000 per acre for site 2
land. Determine how to maximize the government’s revenue.Use
SolverTable to see how changes in the government’s rule on 40% of all
land being auctioned affect the optimal revenue. Why can the optimal
revenue not decrease if this percentage required increases? Why can the
optimal revenue not increase if this percentage required decreases?

Confidence Interval and Testing, statistics homework help
Read the following scenario and complete each of the seven problems below:A new car manufacturing company has emerged and has claimed that its new hybrid car, the Pusho, gets a better gas mileage than the highest ranked Toyota Prius. Consumer Reports Magazine decides to test this claim at a 5% level of significance. Consumer Reports randomly selects 10 of each type of car, calculates the miles per gallon for each car in the study, and records the data in the table below.

Week 4 - Discussion Your initial discussion thread is due on Day 4 (Friday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Refer to the Discussion Forum Grading Rubric under the Settings icon above for guidance on how your discussion will be evaluated. Week 4 In Your World [WLOs: 1, 2, 3, 4] [CLOs: 1, 2, 3, 4, 5] Prior to beginning work on this discussion, read Chapter 9: Modeling Our World and Chapter 10: Modeling with Geometry in your course text, especially pages 532-3 & 536-9. For this discussion, identify three different variables from either recent news stories, the web, or that you encounter in your everyday life. Only one of the variables can be “time” as an independent variable. For inspiration, use the examples listed in the solution to Example 1 on p. 537 of the text, or the Week 4 Discussion Sample, (you must select different examples!). There should be three examples total. After you have identified three different variables, make a table of between 10 and 20 entries of data values for each of your variable pair. Then, graph your data–values, for each variable pair, and describe in words the function that relates the variables. Your initial post should be at least 250 words in length. It should show all the required math work and explain all the steps. Also include a simple reference for any used resource. For example: Washington Post dated August 13, 2018 or retrieved from <url-address>. Your initial discussion thread is due on Day 4 (Friday), and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Carefully review the Grading Rubric for guidance on how your discussion will be evaluated.
