SOLUTION: If Z~N(0,1)find the value of a when: 1. P(Z>a)= 0.3594 2. P(Z<a)= 0.7257 3. P(Z>a)= 0.9382 firstly what does "Z~N(0,1)" mean??? I got these results: 1. a=0.36 2.

Question 458421: If Z~N(0,1)find the value of a when:
1. P(Z>a)= 0.3594

2. P(Z 3. P(Z>a)= 0.9382
firstly what does "Z~N(0,1)" mean???

I got these results: 1. a=0.36
2. a=0.6
3. a= -1.54
right?????
and please can you show me how to gragh the results
and thanks for any help

You can put this solution on YOUR website!
If Z~N(0,1)find the value of a when:
1. P(Z>a)= 0.3594
--------------
Find the z-value with a right tail of 0.3594
----
z = invNorm(1-0.3594) = -0.3601
-------------------------------------
2. P(Z
????
------------------------
3. P(Z>a)= 0.9382
Find the z-value with a right tail of 0.9382
z = invNorm(1-0.9382) = -1.5398
---------------------------------------

firstly what does "Z~N(0,1)" mean???
It means the distribution has mean = 0 and standard deviation = 1.
