For a standard normal distribution, determine the following
probabilities. a) P(z ) >1.39 b) P(z ) > ?0.46 c) P( z )
?1.67? ? ?0.68 d) P( z ) ?1.66? ?0.18 Click here to view page 1 of
the standard normal probability table. Click here to view page 2 of
the standard normal probability table. 3
a) P(z ) (Round to four decimal places as needed.) >1.39 =
0.1056
b) P(z ) (Round to four decimal places as needed.) > ?0.46
=
c) P( z ) (Round to four decimal places as needed.) ?1.67? ? ?0.68
=
d) P( z ) (Round to four decimal places as needed.)
