A government program in a European country is set up to distribute subsidized business loans in towns with a mean independent, single-owned business income below 30,000 euros. Samples of 600 such business are taken from each town. If a town’s mean business income, based on its sample, is calculated as 30,500 euros, with a sample standard deviation of 7,000 euros, should it be disqualified from the program? Why or why not? Base your answer on 95% confidence intervals and ensure that you show your work.

Exercise 3

In the 2012 presidential election, much was made of the Republican candidate’s religion. W. Mitt Romney is a practicing member of the Church of Jesus Christ of Latter-Day Saints. In the 2012 ANES survey, individuals were able to rate parties, candidates, and groups on a 0-100 feel thermometer scale. Measuring their feelings toward members of the LDS church, we calculated:

  • A sample mean of 50.48 degrees
  • A sample standard deviation of 21.90 degrees
  • A sample size of 5,385

Using a 95% confidence interval, what is the range of estimates of the mean from which this sample was drawn. Assume random sampling and ensure that you show your work.
