Hi,

Using the TI Calculator

The syntax is normalcdf(smaller z, larger z).

P(-2.35 ≤ z ≤ -2.33). = normalcdf(-2.35, -2.33).

Or

 P(-2.35 ≤ z ≤ -2.33) =  P(-z ≤ -2.33) - P(2.35 ≤ )

                                  = .0099 - .0094 =highlight%28+.0005%29 = .001 (rounded the decimal to the nearest thousandths place per directions)
