Question

Determine the value of z* such that it 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 94% of all z values from the most extreme 6%.
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 98% of all z values from the most extreme 2%.
z* =

(d) −z* and z* separate the middle 82% of all z values from the most extreme 18%.
z* =
