Walden University Week 6 Red Beads Experiment Discussion
Have you ever worked in a management or leadership position and experienced situations in which employees were not meeting your performance expectations? Or, perhaps you worked under a manager who continually blamed problems of production, output, or sales on you and your colleagues. An important takeaway from the red bead experiment is to consider instances such as these and question whether the fault lies with the employees or with something else, such as management’s decisions or the system that is put in place. As you discuss the red bead experiment, consider how you might be able to relate the lessons learned to your own experiences.In this Discussion, you will examine the red bead experiment and discuss the success of its implementation, as well as how the concepts derived from it can be applied to other aspects of the workplace.Post a 225- to 300-word (3- to 4-paragraph) explanation of how successful the Red Bead experiment was and how an example of the experiment in the workplace can be fixed. In your explanation, address the following:Explain your thoughts on the working climate at the White Bead Company. Describe what the advantages and disadvantages of the inspection system are. Were the strategies that management tried successful in improving workers’ performance? Explain why or why not. Provide an example of a situation similar to the Red Bead experiment that you have experienced in the workplace or have heard someone else describe. Explain how you might improve it. To support your response, be sure to reference at least one properly cited scholarly source.

Central Michigan University Estimating a Population Proportion Statistics Questions
Question 1
In June 2021, Gallup published an online article titled Public Backs Requiring COVID-19 Vaccine to Attend School (Links to an external site.) by Jeffrey M. Jones.
According to the article, 61% of U.S. adults who responded to the survey favor requiring College students to be vaccinated in order to attend classes (including classes in fall 2021). A representative random sample of 3,572 adults U.S. adults, aged 18 and older, were surveyed.
Are conditions met for calculating a confidence interval? Support your conclusion mathematically and show your work.
If conditions are met, use your graphing calculator to calculate a 95% confidence interval that estimates the proportion of U.S. adults who favor requiring College students to be vaccinated in order to attend classes. State your results in context.
Question 2
Login and open StatCrunch (directions).
Open your IAT sample data set in StatCrunch (directions)
We will use a 90% confidence interval to estimate the population proportion of participants born-female in our chosen IAT data set.
So, you are tasked with using your IAT sample to calculate a 90% confidence interval that estimates the population proportion of participants born-female in your particular IAT. But, you are missing a piece of information that would allow you to use your graphing calculator to find the confidence interval. What piece of information is missing?
Even though we cannot readily use our graphing calculators, StatCrunch can calculate the confidence interval for us! Use StatCrunch to find the 90% confidence interval for the population proportion of female participants in your particular IAT (directions - opens in a new tab). Highlight and copy everything in your StatCrunch output window and paste it in your response.
Identify the sample proportion (?? )(p^) in the StatCrunch output table. Then determine whether conditions are met for using the confidence interval to estimate the population proportion of female participants in your chosen IAT. Show your work.
If conditions are met, estimate the population proportion of female participants in your particular IAT, and state your conclusion in context. If conditions are not met, explain what a researcher could do so that conditions are met.
Based on your analysis, do you think the population of participants in your chosen IAT are representative of the U.S. population? Explain https://www.statcrunch.com/app/index.php?dataid=38... THis is the link to my stat crunch table
