Social Security Numbers As part of a project in a statistics class, students report the last four digits of their Social Security numbers, and the average (mean) of those digits is computed to be 4.7.
Part 1 - Estimate the mean price of regular gasoline in the Dayton area by taking a sample.
What is the population you will be studying?
Think carefully about how you are going to get a good sample to calculate a sample mean and collect the sample. For example, driving around your neighborhood is an example of a convenience sample and should not be done. Think of a more efficient way to collect gas prices that will also cover the whole Dayton area. Write a paragraph or two explaining how you collected your sample and why you think your sample is representative of Dayton gas prices.
What is the sample mean?
Construct a 95% confidence interval for the population mean price of gasoline in the Dayton area.
Explain what this confidence interval tells you.
Part 2 - Compare your sample estimate to the current mean gas price in the State of Ohio.

- 2. A drug for treating acne possibly has a side effect of decreasing patients’ sense of self-worth. To test the impact of the acne drug, researchers gather 36 acne patients who are currently taking the acne medicine and give them a survey that measures their feelings of self-worth and self-concept. This sample has a mean self-worth and self-concept of 27. If the mean self-worth and self-concept for population of all people with acne is 32 with a standard deviation of 6, can the researcher confirm that the acne drug lowers patient self-worth? set alpha level at .05 a.

The supervisor of the job placement office at a 4-year college thinks this percentage has increased due to an increased use of technology in the workplace. She takes a random sample of 200 employed adults and finds that 86 of them feel that basic mathematical skills are critical or very important to their job.
