Question 511561: Let z denote a variable that has a standard normal distribution. Determine the value z* to satisfy the conditions below. (Round all answers to two decimal places.)
(a)P(z < z*) = 0.0244
(b)P(z < z*) = 0.0101
(c)P(z < z*) = 0.0494
(d)P(z > z*) = 0.0199
(e)P(z > z*) = 0.0101
(f)P(z > z* or z < -z*) = 0.2038

For each of these you should draw the proper picture
of the problem on a normal curve with horizontal axis z.
That way you will see what you are calculating.
----------------------------
(a)P(z < z*) = 0.0244
z* = invNorm(0.0244) = -1.9899
------------------------
(b)P(z < z*) = 0.0101
(c)P(z < z*) = 0.0494
(d)P(z > z*) = 0.0199
z* = invNorm(1-0.0199) = 2.0558
-----------------------------------
(e)P(z > z*) = 0.0101
(f)P(z > z* or z < -z*) = 0.2038
z* = invNorm(0.2038/2) = -1.2708
