What is the confidence interval

Reference no: EM131397056

1. Assuming random sampling is from a normal distribution with standard deviation σ = 5, if you get a sample mean of X¯ = 45 based on n = 25 participants, what is the 0.95 confidence interval for µ?

1. Repeat the previous example, only compute a 0.99 confidence interval instead.

What values for c should you use in given equation : You want to compute a 0.80, 0.92, or a 0.98 confidence interval for µ when σ is known, and sampling is from a normal distribution, what values for c should you use in Equation (4.8)?

Reflect mathematical principles : Based on the research you will conduct, please write a report describing what you have learned about an artist or musician who used mathematics as part of his/her work. Many musical composers have used mathematics in their compositions. Some artis..

Explain to linda the importance of cost estimation : Also use an example to explain to her the importance of cost estimation. Mickelle is very good at math so she will be interested in the accuracy of visual fit, high-low, or least-squares regression.

Explain factors related to gender that might have contribute : Crime rates show that men have higher victimization rates than women for almost all categories of violent crime except sexual assault (Truman, 2011). Gender differences vary by crime; for example, men are three times more likely than women to be v..

Compute a confidence interval for the mean : For the following situations, (a) n = 12, σ = 22, X¯ = 65, (b) n = 22, σ = 10, X¯ = 185, (c) n = 50, σ = 30, X¯ = 19, compute a 0.95 confidence interval for the mean.

Show consumers how various articles of clothing will fit : Each team member should visit local malls and Web sites and record at least three ways that computers have improved the industry. Compile the findings and then submit a brief report to your instructor.

Express the expected total cost per unit time : When deriving s, explicitly show your approach. That is express the expected total cost per unit time (TC(s)) under the corresponding cost criteria. Then, express DTC(s)=TC(s)-TC(s-1). Describe how one should use DTC(s) to determine optimal s.

Explain what it means to you to be an ethical researcher : As this week's introduction suggested, ethical questions sometimes arise in research and data analysis.
