Use the t-table to identify the area under the t-distribution given the t-value and thenumber of degrees of freedom. Draw a t-distribution for each number then choosefrom BLACK or PINK to shade the required area. (The first one is done for you).Example:Area to the right of 1.746 under a t-distribution with 16 degrees of freedomArea s 0.052.3.1.746START HERE1. Area to the right of 1.323 under a t-distribution with 21 degrees of freedom2. Area to the right of 2.821 under a t-distribution with 9 degrees of freedom3.
