Question

Do one of the following, as appropriate,
a) Find the critical value z_{a/2
b) Find the critical value ta/2
Or c) state that neither the normal (z) nor the t distribution applies.}
95%, n = 11, sigma is known; population appears to be very skewed.

Question 14 options:

a)	Neither the normal nor the t distribution applies

b)	za/2 = 1.96

c)	za/2 = 1.812

d)	ta/2 = 2.228

Answer 1

Ans : Neither the normal nor the t distribution applies

(since population is not normal and n=11<30)
