Based on your selected topic, evaluate the following:

o Find the best point estimate of the population mean.

o Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and ÃÆ’ is unknown. (The symbol should state that the population standard deviation is unknown. Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and ÃÆ’ is unknown. The symbol should state that population standard deviation is unknown.

• Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.

o Write a statement that correctly interprets the confidence interval in context of your selected topic.

3. Based on your selected topic, evaluate the following:

o Find the best point estimate of the population mean.

o Construct a 99% confidence interval for the population mean. Assume that your data is normally distributed and ÃÆ’ is unknown.

• Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.

o Write a statement that correctly interprets the confidence interval in context of your selected topic.

4. Compare and contrast your findings for the 95% and 99% confidence interval.

o Did you notice any changes in your interval estimate? Explain.

o What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain.
