The image contains a table showing the t-distribution values for different degrees of freedom under various levels of significance in the right tail of the distribution. Additionally, there is a graph depicting a t-distribution curve with the shaded area representing the area in the right tail.### Graph Explanation:- **Title**: The graph shows a typical t-distribution curve.- **Shaded Area**: The right tail of the curve is highlighted, indicating the area for which the values in the table are calculated.### Table Details:- **Columns**: The table lists t-values at specific significance levels (0.25, 0.20, 0.15, 0.10, 0.05, 0.025, 0.02, 0.01, 0.005, 0.0025, 0.001, 0.0005) for various degrees of freedom.- **Rows**: Each row corresponds to a different degree of freedom starting from 1 up to 1000 and includes an additional row for infinity.- **Values**: Each cell in the table represents the t-value for the specified degree of freedom and significance level.This table is typically used in statistics to determine critical values for hypothesis testing involving t-distributions, commonly used in estimating population parameters when the sample size is small and the population standard deviation is unknown. The following data represent the pH of rain for a random sample of 12 rain dates. A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot indicates there are no outliers.
