Determine the value of z* such that satisfies the conditions below. (assume that the requested value of z* is positive. round your answers to two decimal places.)
(a) −z* and z* separate the middle 95% of all z values from the most extreme 5%
z* =

(b) −z* and z* separate the middle 85.3% of all z values from the most extreme 14.7%
z* =

(c) −z* and z* separate the middle 97.8% of all z values from the most extreme 2.2%
z* =

(d) −z* and z* separate the middle 92% of all z values from the most extreme 8%
z* =
