Study Notes
- Using the t distribution table to obtain t critical values involves selecting rows for the tail type, columns for significance levels, and rows for degrees of freedom.
- In a left-tailed distribution with a significance level of 0.10 and 14 degrees of freedom, the t critical value is -1.345.
- For a right-tailed distribution with a significance level of 0.05 and 24 degrees of freedom, the t critical value can be found by selecting the appropriate values.
- In a two-tailed distribution with a significance level of 0.01 and 34 degrees of freedom, the process of selecting the t critical value follows a similar pattern as in the other examples.
Learn how to obtain t critical values using the t distribution table by selecting rows for the tail type, columns for significance levels, and rows for degrees of freedom. Practice left-tailed, right-tailed, and two-tailed distributions with different significance levels and degrees of freedom.
