Question 1150422
Find the z-score where the area to the left of z is 0.9500.  (This is the same z-score where the area to the right of z is 0.0500.)  The z-score where this occurs is at 1.645.
<pr>
{{{(x - mean)/SD}}} = 1.6450
<pr>
{{{(x - 7)/2}}} = 1.6450
<pr>
Cross-multiply:
<pr>
x - 7 = 2(1.6450)
<pr>
Simplify and solve for x:
<pr>
x - 7 = 3.2900
<pr>
x = 10.2900
