Do one of the following, as appropriate. (a) Find the critical value z Subscript alpha divided by z/2, (b) find the critical value t Subscript alpha divided by 2t/2, (c) state that neither the normal nor the t distribution applies. Confidence level 9898%; nequals=1818; sigma is unknown is unknown; population appears to be normally distributed.

a. t OF alpha = 2567

b. 2.33

c. 2.055

d. 2.224

neather normal nor at distribution applies.
