1. List all the class responses to your survey question in ascending order.

How many people do you think I have living with me?

3+2+3+3+4+3+2+4+4+4+4+3+5+3+4+3+4+0+0+2+4+4+3+4+2+4+3+6+0+3+5+5+2+4+2+3+5

2. What is the best point estimate for your survey question that you used? Be sure to include both the correct notation (symbol) and the value.

3. Construct a confidence interval for the responses to your survey. Assume that you do not know the population standard deviation.

4. Indicate your level of confidence and the corresponding critical value.

5. What is the margin of error?

6. If we would increase the sample size to 500 students, what would happen to your margin of error?
