TOPIC 5: Identifying percentiles using the t-table.Activity 1.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 = 0.053.1746START 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. Area to the left of -2.179 under a t-distribution with 12 degrees of freedom4. Area to the left of 0.889 under a t-distribution with 8 degrees of freedom5. Area to the right of 1.25 under a t-distribution with 25 degrees of freedom?Activity 2.Answer the following problems.1. Find the values of t for which the area on the right tail of the t-distribution is 0.05and the number of degrees of freedom is equal to:a. 15b. 28с. 1002. Find the 99th percentile of the t-distribution with 18 degrees of freedom.3. Find the 90th percentile of the t-distribution if the sample size is 25.ADNESSHELORGLADNES(9)
