Q (a) z = 1.268 (b) z= - 1.376 (C) Z= - 1.449 (d) z= - 1.149 -20 = -1.285 0 (a) For z = 1.268, should you reject or fail to reject the null hypothesis? O A. Reject Ho because z > - 1.285. O B. Reject Ho because z - 1.285. O D. Fail to reject Ho because z - 1.285. O D. Reject Ho because z > - 1.285. (c) For z= - 1.449, should you reject or fail to reject the null hypothesis? O A.
