Statistics discussion post
Assume that you are interested in doing a statistical survey and using confidence intervals for your conclusion. Describe a possible scenario and indicate what the population is, and what measure of the population you would try to estimate (proportion or mean) by using a sample.
- What is your estimate of the population size?
- What sample size will you use? Why?
- How will you gather information for your sample? Describe your process.
- What confidence percentage will you use? Why?
Student example: For this discussion, I will like to determine the number of state employees working in the city of Tallahassee, FL. The city has a population of 181,376, in order to calculate the percentage of state employees I will have to use a sample size of 1061 assuming the population was sampled without replacement and with a proportion on 0.5 with a confidence percentage of 95%. I will use a 95% confidence percentage because 99% confidence would be wider. I will gather this information by taking a survey at the local state entities in the city, also by researching information through the local employment agencies such as People First the main state of Florida employment site and the department of labor.
Using a 95% confidence level it is determined that 21% to 38% of the city of Tallahassee population is a state employee.
