Given that z is a standard normal random variable, compute the probability that it takes on a value that is: - either greater than 2 or less than -2. - that it takes on a value between -2 and -1. - that it takes on a value between 1 and 2. Answer must be between 0 and 1, round to four decimal places.
a) Find the value of the probability of the standard normal variable Z corresponding to the shaded area under the standard normal curve. (Round your answer to four decimal places. You may need to use the appropriate table in the Appendix of Tables to answer this question.)
