do one of the following as appropriate: a) find the critical value z a/2, b) find the critical value t a/2, c) state that neither the normal nor the t-distribution applies. Confidence level is 95%. n=28. o is known. Population appears to be very skewed.
A). Za/2 = 1.96
B). Za/2 = 1.645
C). ta/2 = 2.052
D). ta/2 = 1.703
E). Neither normal nor t distribution applies.

D). ta/2 = 1.703
E). Neither normal nor t distribution applies.
Solution
a) critical value z a/2 at 95% level is 1.96
b) critical value t a/2 at 95% level and 27 df is 2.052
c) Population appears to be very skewed. then Neither normal nor t distribution applies.
