As its name implies, confidence intervals provide a range of values, along with a level of confidence, to serve as an estimate of some unknown population value. Since it is rare to have access to the entire population, you must frequently rely on the confidence interval of the sample to make some inference about the population of interest. Before making accurate inferences to the population, we need to fully understand how the three key components of the interval—variability in the data, sample size, and confidence level—impact the width of the interval.For this Discussion, you will explore the relationship between these components and understand the trade-off between reducing risk in our confidence of estimates and increasing precision.To prepare for this Discussion:Review Chapters 6 and 7 of the Frankfort-Nachmias & Leon-Guerrero text and in Chapter 7, p. 188, consider Hispanic migration and earnings and focus on how different levels of confidence and sample size work together.Review Magnusson’s web blog found in the Learning Resources to further your visualization and understanding of confidence intervals.Use the Course Guide and Assignment Help found in this week’s Learning Resources to search for a quantitative article related to confidence intervals.Using the SPSS software, General Social Survey dataset and choose a quantitative variable that interests you.By Day 3Using SPSS:Take a random sample of 100.Calculate the 95% confidence interval for the variable.Calculate a 90% confidence interval.Take another random sample of 400.Calculate the 95% confidence interval for the variable.Calculate a 90% confidence interval.Post your results and an explanation of how different levels of confidence and sample size affect the width of the confidence interval. Next, consider the statement, “Confidence intervals are underutilized” and explain what the implications might be of using or not using confidence intervals. Provide examples based on the results of your data. Also, use your research to support your findings.

Throughout history, there have been women and men who exhibited exemplary behavior. We often look to famous people as role models and build statues or post plaques in their honor. Life is, however, full of often unheralded lives that have demonstrated positive values and engaged citizenship. Whether it’s Miguel Keith, an 18-year-old Hispanic Marine from Omaha who was posthumously awarded the Congressional Medal of Honor for bravery in combat, or the Civil Rights leader and Nebraska Hall of Fame member, Standing Bear, or perhaps someone you know, there are many role models in society.This week’s assignment is to nominate someone you know to the fictitious, Engaged Citizenship Hall of Fame. For this assignment, consider the values presented in the assigned reading articles from Week 1 through Week 6. Compose an appropriate tribute arguing that this person’s behavior exhibited one or more of the values examined in the course. If possible, include a photograph or some other appropriate image to represent the person you are nominating. Avoid overly hyperbolic or emotive attributes.
