Explain in APA format how different levels of confidence and sample size affect the width of the confidence interval.

I am in need of assistance with an assignment question focusing
 solely on the age variable previously deliverd General Social Survey dataset  along with codebook.  Would you be willing to assist?  If this works well, future work to come. I hope to submit later today.

Kindly also offer navigation so that I may replicate results

Instructions below

  • Review Chapters 7 & 8 of the Frankfort-Nachmias & Leon-Guerrero text and in Chapter 8, p. 256, consider the 2012 Benghazi Terrorist Attack Investigation and focus on how different levels of confidence and sample size work together.
  • Review Magnusson’s web blog at http://rpsychologist.com/index.html  to further your visualization and understanding of confidence intervals.

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.

Explain in APA format how different levels of confidence and sample size affect the width of the confidence interval.   Also consider the following, “Confidence intervals are underutilized”.  Explain the implications for using or not using  confidence intervals.  Examples would be good as well.  Charts/graphs in APA format as well.

Thank you
