Explanation & Answer
You have to find the value of y which will make the equation 0.
(4u - 7)(9 - u) = 0
4u - 7 = 0 or 9 - u = 0
4u = 7 or -u = -9
u = 7/4 or u = 9

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

University of Phoenix Statistics ANOVA Analysis Excel and Presentation
You are in charge of conducting an analysis for your organization to determine if there is a difference in product sales between the day shift, the night shift, and the weekend shift. Your coworker has already collected the data and they are ready for you to analyze.Review the data your coworker collected in the Analysis of ANOVA Test Data Spreadsheet.
First, plan your analysis. Second, conduct your analysis. Third, describe your analysis.
Create a 5- to 7-slide Microsoft® PowerPoint® presentation and include speaker notes. Include the following elements in your presentation.
Part 1: Planning
What are the null and alternative hypotheses?
Where did you obtain your data or who obtained it for you?
Part 2: Analysis
What are the descriptive statistics for your sample? Include:
Sample size
Mean
Median
Mode
Standard deviation
Analysis procedures: What did you do to conduct your analysis?
Part 3: Results and Discussion
What are the test statistics and results? Include
f statistic
p-value
What are the results? Are the results inferable to the population?
Do you reject or fail to reject the null hypothesis? Explain.
What do the results mean? What is your recommendation to the organization?
