Determine the t-value in each of the cases. LOADING... Click the icon to view the table of areas under the t-distribution. (a) Find the t-value such that the area in the right tail is 0.10 with 15 degrees of freedom. 1.341 (Round to three decimal places as needed.) (b) Find the t-value such that the area in the right tail is 0.01 with 27 degrees of freedom. 2.473 (Round to three decimal places as needed.) (c) Find the t-value such that the area left of the t-value is 0.20 with 14 degrees of freedom. [Hint: Use symmetry.] negative 0.868 (Round to three decimal places as needed.) (d) Find the critical t-value that corresponds to 99 % confidence. Assume 13 degrees of freedom. nothing (Round to three decimal places as needed.)

Explanation / Answer

a) t-value such that the area in the right tail is 0.10 with 15 degrees of freedom =1.341

b)  t-value such that the area in the right tail is 0.01 with 27 degrees of freedom =2.473

c) t-value such that the area left of the t-value is 0.20 with 14 degrees of freedom.=-0.868

d) critical t-value that corresponds to 99 % confidence = - /+ 3.012
