Question:

(a) Find the t-value such that the area in the right tail is 0.02 with 19 degrees of freedom.
(b) Find the t-value such that the area in the right tail is 0.10 with 32 degrees of freedom.
(c) Find thet-value such that the area left of thet-value is 0.05 with 6 degrees of freedom.
(d) Find the critical t-value that corresponds to 95% conﬁdence.Assume 16 degrees of freedom.
