# Solution: Identifying P-values for Each Quantile Plot ## Understanding the Shapiro–Wilk Test and Q-Q Plots The **Shapiro–Wilk test** is used to check whether a data set is approximately normally distributed. The null hypothesis (H₀) assumes normality. - **High p-value** (commonly > 0.05): Fail to reject H₀; data likely normal. - **Low p-value** (commonly < 0.05): Reject H₀; data **not** normal. A **Q-Q plot** (quantile-quantile plot) visually compares data distribution with a normal distribution: - **Data points close to the line**: Data is approximately normal. - **Data points far from the line, with curves or S-shapes**: Data is not normal. Two p-values are given: **0.235** and **0.00015**. --- ## Step-by-Step Analysis ### **Plot (a) Analysis** - In plot (a), most points **deviate significantly** from the straight line, especially at the ends. - This pattern shows **strong evidence against normality**. ### **Plot (b) Analysis** - In plot (b), points **closely follow the straight line**, with only slight deviations. - This pattern suggests the data is **approximately normal**. --- ### **Assignment of P-values** #### **Plot A: p-value would be: 0.00015** **Reason (required):** Plot (a) shows points that deviate markedly from the straight line, indicating non-normality. The Shapiro–Wilk test would produce a **very low p-value (0.00015)**, suggesting strong evidence against the data being normally distributed. #### **Plot B: p-value would be: 0.235** **Reason (required):** Plot (b) shows points that closely follow the straight line, demonstrating approximate normality. The Shapiro–Wilk test would produce a **higher p-value (0.235)**, indicating no significant evidence against normality. --- ## **Summary Table** | Plot | p-value | Reason | |--------|-----------|-----------------------------------------------------------------------------------------| | (a) | 0.00015 | Strong deviation from normal line; data is not normal. | | (b) | 0.235 | Points closely follow the normal line; data is approximately normal. | --- ### **Best Interpretation** A **low p-value** in the Shapiro–Wilk test matches a plot that deviates from normality (plot a), while a **higher p-value** indicates a plot that resembles a normal distribution (plot b). --- ## **Final Answer** - **Plot A: p-value would be: 0.00015** - **Plot B: p-value would be: 0.235** Plot (a) corresponds to the lower p-value due to its strong non-normality, while plot (b) matches the higher p-value, reflecting its approximate normality.
