    The z-value is 1.  You overthought this one.

    z is the value on the x-axis, under the bell curve. So it's just (35-30)/5 = 1

    My table defines z as the area under the curve from 0 to z, in which case z would not have the 0.5 added to it; just 0.3413.  Is that it?  And in any case, this is rounded to 4 decimal places but the directions call for an exact value?
