Question 1 (1 point) Saved Let X1, ... , Xn be a random sample from some population with Ex2 = 34334, Ex = 9.43. 3446 and n= 359. Suppose I want to test the hypothesis Ho: M = 9.43 against Ha: * (Please choose the best answer.) a) Then z=1.708 and I would not reject at a = 0.05. b) Then z=1.708 and I would reject at a = 0.05. c) Then z=1.809 and I would not reject at a = 0.05. O d) Then z=0.065 and I would not reject at a = 0.05. O e) Then z=1.809 and I would reject at a = 0.05.
