6.2 Given a standardized normal distribution (with a mean of 0 and a standard deviation of 1, as in Table E.2), what is the probability that a. Z is between -1.57 and 1.84? b. Z is less than -1.57 or greater than 1.84? c. What is the value of Z if only 2.5 percent of all possible Z values are larger? d. Between what two values of Z (symmetrically distributed around the mean) will 68.26 percent of all possible Z values be contained?
