Suppose that a friend of yours says that they were reading about confidence intervals and ask you the following questions:Part 1When they encountered the symbols a and mu (u) they ask "What's the difference between what these symbols represent, and what does thathave to do with confidence intervals?" (make sure you answer both parts of the question).1.Part 2When building a confidence interval, we use a point estimate and margin of error. Explain what these two terms mean, and discuss how themargin of error is related to the sample size.

Here's, x-bar and mu, first of all x-bar is the sample mean and mu is the population mean. We use…

HELP WITH BOTH QUESTIONS THAT GO WITH PICTURE.. Question 1: What is the confidence interval for the population mean μ? _____hg <μ<_____ hg (Round to one decimal place as needed.) Question 2: Are the results between the two confidence intervals very different? A. Yes, because the confidence interval limits are not similar. B. Yes, because one confidence interval does not contain the mean of the other confidence interval. C. No, because each confidence interval contains the mean of the other confidence interval. D. No, because the confidence interval limits are similar.
Lorraine was in a hurry when she computed a confidence interval for μ. Because σ was not known, she used a Student's t distribution. However, she accidentally used degrees of freedom n instead of n − 1. Will her confidence interval be longer or shorter than one found using the correct degrees of freedom n − 1? Explain. Longer. As the degrees of freedom increase, the value for tc increases.Shorter. As the degrees of freedom increase, the value for tc increases. Shorter. As the degrees of freedom increase, the value for tc decreases.Longer. As the degrees of freedom increase, the value for tc decreases.
