Florida Southwestern College Identify One Qualitative and Two Quantitative Variables Discussion 2
I’m working on a statistics discussion question and need support to help me understand better.
Tell us about your chosen career. My chosen career is a professional chef, Identify three variables, one qualitative and two quantitative, that would be vital for your responsibilities in your chosen career. Select two quantitative variables that you believe are related in some way (think correlation).
Please answer these questions for this assignment:
How you would collect the data?
What permission(s) you need to conduct the data collection?
What sample size is appropriate and possible?
What measures of central tendency and dispersion would be appropriate?
What tables and graphs could be used to represent the data?
Why would you choose to collect these variables?
What relationship do you believe exists between the two quantitative variables? Why?

Pasadena City College Hypothesis Test Statistics Calculations
Student Learning Outcomes
The student will use and derive fundamental concepts from the given information
The student will develop a stronger understanding of calculations behind hypothesis testing.
The student will determine the unknown value by utilizing the acquired knowledge on hypothesis testing.
Introduction
Let’s assume a theoretical scenario. Let’s assume that we are asked to determine if a new plant treatment helps a certain species of plant to grow taller. We will only accept success if more than 50% of the treated plant grow taller. In this exercise it is irrelevant what the size of the plant is.
225 plants were treated in this example. The following results for a hypothesis test on proportion is given:
Ha: p>0.5p>0.5
H0: p=0.5p=0.5
We get that the p-value= 0.025
Question
Given that x = number of plants that grew taller, and in light of the above information find:
the number (x)(x) of plants that grew taller and
the success rate (p?)(p?) of plants that grew taller
Project Guidelines
Z-Test Statistic
p-value measures the area to the right of the test statistic. What is the z-value that has the given p-value?
Formula
Remember the calculation for the distance of the observed value to the null hypothesis.
z=p??pp?(1?p)n?z=p??pp?(1?p)n
Response
Submit your response by direct text entry OR by uploading a PDF of your work.
The submission should contain:
Evidence of the appropriate calculations that helped you derive the answer to the problem
Neatly organize your notes and evidence
provide the calculator/computer function that you used in order to determine your answers
Walden University Wk 3 Standard Deviation Units Exercises
Submit your responses to the following prompts.
A market-research firm was hired to determine the percentage of people in a market area who would purchase a client’s magazine if a door-to-door sales campaign were undertaken. The firm stated that 40% would buy if contacted at home. Suppose the marketing company has tried the sales campaign at 300 randomly selected homes. (150–225 words, or 2–3 paragraphs)
Assuming the market research was done properly and the 40% is representative, how many sales are expected if the publisher attempts to sell to 5,000 homes?
If the market research was accurate, what is the probability that fewer than 100 individuals will buy? Use the normal approximation to the binomial.
Suppose that the publisher actually sells the magazine to 70 people out of the 300 contacted. What would you conclude about the market research? About the campaign?
A steel mill produces alloy sheets used for the bodies of automobiles. The mill produces sheets with an average thickness of 0.517 inches and a standard deviation of 0.037 inches. A new car model requires alloy sheets between 0.495 and 0.525 inches thick. What percentage of the sheets made by the mill will be suitable for the new car model? Explain your answer. (75 words, or 1 paragraph)
The VP of HR for a large company is interested in the distribution of sick-leave hours for employees at the company. A recent study revealed that the distribution was consistent with a normal model, with a mean of 58 hours per year, and a standard deviation of 14 hours. An office manager of one division believes that during the past year, two of the division’s employees have taken excessive sick leave. One took 74 hours and the other used 90 hours. What would you conclude about the division manager’s claim, and why? (75 words, or 1 paragraph)
Each month, an American household generates an average of 28 pounds of newspaper for garbage and/or recycling. Assume this is approximately normally distributed and that the standard deviation is 2 pounds. If a household is selected at random, find the probability of it generating between 27–31 pounds per month. (75 words, or 1 paragraph)

SWK 530 Florida International Qualitative and Quantitative Study Discussion
Using the same subject/topic you selected in the “homelessness as a social issue for the mentally ill” assignment:
Part One
Think about the topic that you have been looking at thus far and come up with a qualitative piece for it. Think about what type of question or questions you might want to ask of the data that would lend itself more qualitatively. Meaning, come up with one or two qualitative research questions.
Come up with a list of 10 open-ended questions that you would want to ask your target population if doing an interview with each person.
Explain the reasons why qualitative data would be good for this piece and what can it bring to the table that quantitative cannot.
Part Two
Please repeat the quantitative research question that you should have already come up with or have been working with so far. Briefly discuss those variables in that question and operationally define those. (i.e., when we operationally define a variable, it is how we are going to measure that variable in our study. We can find how to do that by looking at how others have done it in previous studies. How these are defined need to be seen in the questions in our survey.)
Develop a survey based on all the suggestions in the chapters and how you have operationally defined the variables in the question above. Make sure to have 20 questions and do not forget the scale. You need to have the question/statement and the scale needs to be out to the side of EACH of these questions/statements that you have. Please remember to put directions on this.
Discuss what this could bring to your study that qualitative data could not.
CSU Global Campus Algebra Cost of Fencing a Garden Problem
As a property owner, you want to fence a garden which is adjacent to a road. The fencing next to the road must be stronger and cost $6 per foot. The fencing on the other sides cost $4 per foot. The area of garden is 2400 square feet.
Draw several diagrams to express the situation and calculate the cost for each configuration, and then estimate the dimension of minimum cost.
Find the function that represents the cost in terms of one of its sides.
Using the graphing utility, graph this cost function
Find the dimension that minimizes the cost of fencing and compare this with your estimate based the diagram you made.
Requirements:
Your paper should be 2-3 pages in length (not counting the title page and references page) and cite and integrate at least one credible outside source. The CSU Global Library (Links to an external site.) is a great place to find resources. Your textbook is a credible resource.
Include a title page, introduction, body, conclusion, and a reference page.
The introduction should describe or summarize the topic or problem. It might discuss the general applications of the topic or it might introduce the unique terminology associated with the topic.
The body of your paper should address the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure this is in paragraph format, not numbered answers like a homework assignment.
The conclusion should summarize your thoughts about what you have determined from your analysis in completing the assignment. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs.
Include any tables of data or calculations, calculated values, and/or graphs referenced in the paper. (Note: The minimum required length excludes any tables, graphs, etc.)
