If you were supposed to do this the old fashioned way, using tables only, tell
me in space at the bottom, and I'll get back to you by email.  This is by using
a graphing calculator.

On your newer TI-84

2ND VARS 
Scroll with down arrow to highlight 3:invNorm
ENTER
area:0.11
μ:0
σ:1
Tail: LEFT  CENTER  RIGHT
Scroll with right arrow to highlight RIGHT
ENTER
Scroll with down arrow to highlight Paste
ENTER
see this invNorm(0.11,0,1,RIGHT)
ENTER
Answer:    z=1.22652812

---------------------

On older TI-83 or 84

invNorm(1-0.11,0,1)

---------------------

What the answer z=1.22652812 means:



The green shaded part is 11% of the total area between the standard normal curve
and the z-score axis (the horizontal axis).
