Given that z is a standard normal random variable, compute the probability that it takes on a value between 1 and 3.
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.
