You obtain a sample of size $ n = 621 $ with mean $ M = 71.5 $ and a standard deviation of $ SD = 19.5 $.### Steps to Perform the Test:1. **Calculate the Test Statistic:** What is the test statistic for this sample? (Report answer accurate to three decimal places.) \[ \text{test statistic} = \_\_\_\_\_ \]2. **Determine the p-value:** What is the p-value for this sample? (Report answer accurate to four decimal places.) \[ \text{p-value} = \_\_\_\_\_ \]### Decision Making Based on p-value:- The p-value is... - ○ less than (or equal to) $ \alpha $ - ○ greater than $ \alpha $This test statistic leads to a decision to... - ○ reject the null - ○ accept the null - ○ fail to reject the null### Conclusion:As such, the final conclusion is that... - ○ There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.9. - ○ There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 69.9. - ○ The sample data support the claim that the population mean is not equal to 69.9. - ○ There is not sufficient sample evidence to support the claim that the population mean is not equal to 69.9.---### Explanation of the Calculations:1. **Test Statistic Calculation:** The test statistic can be calculated using the formula for the one-sample z-test: \[ z = \frac{M -

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
