The probability that Z is between negative 1.54 and 1.89 is 0.9088. The probability that Z is less than negative 1.54 or greater than 1.89 is 0.0912. The value of Z if only 10​% of all possible Z values are larger is 2.33. Between what two values of Z​ (symmetrically distributed around the​ mean) will 80.64​% of all possible Z values be​ contained?
