Finding standard deviation

7. A recent survey of Fortune 500 firms found that on average, they contribute
$332.54 per month for each salaried employee’s health insurance. If you are told
that almost all salaried employees at Fortune 500 firms receive a health insurance
contribution between $220.61 and $444.47, what must the standard deviation for
this data be? Assume that the distribution is approximately mound-shaped.
A) $37.31
B) $46.65
C) $55.98
D) $74.64

The process of random sampling guarantees that the sample selected will be representative of the population.

Walden University Police and Presence of Democracy Statistics Question

Assignment: Testing for Bivariate Categorical AnalysisYou have had plenty of practice with data analysis in the Discussions and hopefully, you have received helpful and encouraging feedback from your colleagues. Now, for the last time in the course, it is time once again to put all of that good practice to use and answer a social research question using categorical statistical tools. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure the variables are categorical level variables.For this Assignment, you will consider three different scenarios. Each of these scenarios include a research question. You will examine each scenario, choose a categorical data analysis and run a sample test.To prepare for this Assignment: Review Chapters 10 and 11 of the Frankfort-Nachmias & Leon-Guerrero course text and the media program found in this week’s Learning Resources related to bivariate categorical tests. Using the SPSS software, open the Afrobarometer dataset found in this week’s Learning Resources. Next, review the Chi-Square Scenarios found in this week’s Learning Resources and consider each research scenario for this Assignment. Based on the dataset you chose and for each research scenario provided, using the SPSS software, choose a categorical data analysis and run a sample test. Once you perform your categorical data analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 1- to 2-paragraph analysis of your categorical data results for each research scenario. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.

MATH 122 CSU Global Algebra: Quantity and Pricing

Option #2: Quantity and PricingAs a manager, you have the following data collected by your data analyst regarding the price and quantity demanded.PriceQuantity Demanded35003270330037963100435529004951280052652650575724006640Using a graphing utility, draw a scatter diagram with price as a function of demand.Using a graphing utility, build a logarithmic model from the data.Graph the logarithmic function in the scatter diagram.Use the function you found in the second bulleted item to predict the number of quantities that will be demanded if the price is $1750. Round to the nearest whole number.Use the function you found in in the second bulleted item to predict the price, if the quantity demanded is 174. Round to the nearest whole number.Requirements:Paper must be written in 3rdYour paper should be 4-5 pages in length (counting the title page and references page) and cite and integrate at least one credible outside source. 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 importance of the topic or how it affects you or society as a whole, or it might discuss or describe the unique terminology associated with the topic.The body of your paper should answer 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 the data and your analysis, often with a broader personal or societal perspective in mind. 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 associated with this problem in the body of your assignment.Document formatting, citations, and style should conform to the APA standard.
