Find P(z>-2.575).
a. 0.0050
b. 0.6500
c. 0.1950
d. 0.9950
Solution :
P(Z > -2.575 ) = 1 - P(Z < -2.575) =
Using standard normal table
P(Z < z) =
To see the z value - 0.2 in the column and 0.575 in the row of the
standard normal table the corresponding probability is
= 1 - P(Z < - 2.575 )
= 1 - 0.0050
= 0.9950
Probability = = 0.9950
Option d ) is correct.
Find a. P(Z=1.32) b. P(Z>5) c. P(-1<Z<1) d. P(-2<Z<2) e. P(-3<Z<3) (c, d, and e form what is called the Empirical Rule. Look it up!) f. The 20th percentile of Z g. The z value with 5% area to its right. please show all work not just answers and do all of them please and thank you will rate high
