Activity 1. Use the t-table to identify the area under the t-distribution given the t-value and the number of degrees of freedom. Draw a t-distribution for each number then choose from 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 freedom Area a 0.05 1746 START HERE 1. Area to the right of 1.323 under a t-distribution with 21 degrees of freedom 2. Area to the right of 2.821 under a t-distribution with 9 degrees of freedom 3. Area to the left of -2.179 under a t-distribution with 12 degrees of freedom 4. Area to the left of 0.889 under a t-distribution with 8 degrees of freedom 5. Area to the right of 1.25 under a t-distribution with 25 degrees of freedom?

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 the number of degrees of freedom. Draw a t-distribution for each number then choose from 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 freedom Area = 0.05 3. 1746 START HERE 1. Area to the right of 1.323 under a t-distribution with 21 degrees of freedom 2. Area to the right of 2.821 under a t-distribution with 9 degrees of freedom 3. Area to the left of -2.179 under a t-distribution with 12 degrees of freedom 4. Area to the left of 0.889 under a t-distribution with 8 degrees of freedom 5. 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 0.05 and the number of degrees of freedom is equal to: a. 15 b. 28 с. 100 2. 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. ADNESS HE LOR GLADNES (9)
