Given the image, the text is a statistical analysis problem involving Anova (Analysis of Variance) to determine if there is a difference in the population mean three-circle red-on-white sherd counts across four archaeological sites.**Data Table:**- **Site I:** {12, 7, 14, 22, 6}- **Site II:** {32, 23, 19}- **Site III:** {5, 9, 24, 31}- **Site IV:** {10, 4, 21, 30, 17}**Problem Steps:**1. **Level of Significance:** Use a 10% level of significance.2. **Hypotheses:** - \( H_0 \): \(\mu_1 = \mu_2 = \mu_3 = \mu_4\) (All means are equal.) - \( H_1 \): Not all the means are equal.3. **Sum of Squares Computation:** - Calculate \( SS_{Total} \), \( SS_{Group} \), and \( SS_{Error} \). - Use 3 decimal places.4. **Degrees of Freedom:** - \( df_{between} \) (numerator) - \( df_{within} \) (denominator)5. **F-Statistic:** - Compute and find the value of the sample F statistic (3 decimal places).6. **P-Value:** - Determine and use 4 decimal places.7. **Decision Making:** - Based on \( \alpha = 0.1 \), decide whether to reject \( H_0 \).8. **Conclusion Interpretation:** - Options for interpreting your decision on the means of the groups.9. **ANOVA Summary Table:** - A blank table is provided for you to enter the Source of Variation, Sum of Squares, Degrees of Freedom, Mean Square, F-Ratio, P-Value, and Test Conclusion.This content assists students in practicing their understanding of ANOVA calculations and hypothesis testing in statistical analysis.

Medical researchers want to know if Tylenol, Advil, Ibuprofen, and Aleve different medications lead to different mean pain level reductions in patients. They randomly assign 20 patients to use each medication for one month, then measure the pain level both before and after the patient started using the medication to find the mean pain level reduction for each medication. To understand whether there is a statistically significant difference in the mean pain level reduction that results from these medications, researchers can conduct a one-way ANOVA, using “type of medication” as the factor and “pain level reduction” as the response. If the overall f-value of the ANOVA is lower than our significance level, then we can conclude that there is a statistically significant difference in mean pain level reduction between the four medications. a.Identify the Dependent Variable and Independent variable including the levels. b.What is the df between, df within, and df total?
