Find the value of t for the t distribution for each of the following. (a) Area in the right tail =0 .05 and df= 12 (b) Area in the left tail =0.975 and n = 61 (c) Find the value of t for the t distribution with 37 degrees of freedom and 0.1 area in the left tail.
(a) Find the t-value such that the area in the right tail is 0.20 with 13 degrees of freedom (b) Find the t-value such that the area in the right tail is 0.25 with 27 degrees of freedom (c) Find the t-value such that the area left of the t-value is 0.02 with 24 degrees of freedom. d) Find the critical t-value that corresponds to 80% confidence. Assume 27 degrees of freedom.
