Discuss the importance of constructing confidence intervals for the population mean.
- What are confidence intervals?
- What is a point estimate?
- What is the best point estimate for the population mean? Explain.
- Why do we need confidence intervals?

Based on your selected topic, evaluate the following:
- Find the best point estimate of the population mean.
- Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and ? 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.
- Write a statement that correctly interprets the confidence interval in context of your selected topic.

Based on your selected topic, evaluate the following:
- Find the best point estimate of the population mean.
- Construct a 99% confidence interval for the population mean. Assume that your data is normally distributed and ? 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.
- Write a statement that correctly interprets the confidence interval in context of your selected topic.

Compare and contrast your findings for the 95% and 99% confidence interval.
- Did you notice any changes in your interval estimate? Explain.
- What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain.

Discuss the process for hypothesis testing.
- Discuss the 8 steps of hypothesis testing?
- When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?

Perform the hypothesis test.
- If you selected Option 1:
  - Original Claim: The average salary for all jobs in Georgia is less than $65,000.
  - Test the claim using ? = 0.05 and assume your data is normally distributed and ? is unknown.

If you selected Option 2:
- Original Claim: The average age of all patients admitted to the hospital with infectious diseases is less than 65 years of age.
- Test the claim using ? = 0.05 and assume your data is normally distributed and ? is unknown.

Based on your selected topic, answer the following:
1. Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.
2. Is the test two-tailed, left-tailed, or right-tailed? Explain.
3. Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.
4. What is the value of the test-statistic? What is the P-value?
  What is the critical value?
5. What is your decision; reject the null or do not reject the null?
  1. Explain why you made your decision including the results for your p-value and the critical value.
6. State the final conclusion in non-technical terms.

Conclusion
- Recap your ideas by summarizing the information presented in context of your chosen scenario
