P%28z%3E=1.96%29=1-P%28z%3C1.96%29
Use the normal distribution table or NORMSDIST in EXCEL to find P%28z%3C1.96%29

P%28-1.35+%3C=z%3C=+1.35%29=P%28z%3C1.35%29-P%28z%3C-1.35%29
Use the normal distribution table or NORMSDIST in EXCEL to find the probability values.

P%281.22+%3C=z%3C=+2.47%29=P%28z%3C2.47%29-P%28z%3C1.22%29
Use the normal distribution table or NORMSDIST in EXCEL to find the probability values.
