Question

In this word problem you will be given a sample of data from a normal population along with a confidence level. It is your project to define what variable that sample data represents, and what the population is that your t-Interval will make an inference on. Given the following data, create your own word problem and answer the following questions. (1-6)

Sample data: 1.3, 1.7, 1.7, 2.0, 2.3, 2.3, 2.7, 3.0, 3.0, 3.0, 3.3, 3.3, 3.7, 3.7, 4, 4

Confidence level: 90%

1. What is the point estimate? (show work)
2. What is the t_α/2 given 90% confidence?
3. What is s?
4. What is the margin of error? Interpret this value. (show work)
5. What is the 90% confidence interval? (show work)
6. Interpret the 90% confidence interval. Be sure to label units and to name the population mean.

Your word problem has no limits, other than it must be completed individually, accurate with our material and school appropriate. The application/scenario that you create can be as creative as imaginable, therefore the numbers could potentially be unrealistic to your scenario.
