Question 44657: Hi I am stumped with this
Let Z be a standard normal random variable, dtermine the value of c such that
p(-c _< Z _ Carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal places
Answer by stanbon(48568) About Me  (Show Source):
You can put this solution on YOUR website!
p(-c _< Z _ How you do this problem depends on how your "Z-chart"
is set up.
If it gives you area values only to the right of z=0
you want the z value that corresponds to an area of
0.9668/2 = 0.4834 to the right of z=0.
That z-value is 2.212965...
If you are using a TI calculator you want
InVNorm(0.9668)
