We find the z-score that corresponds with this situation. Z-scores are found using the formula:
Using our information we have:
Using a z-table (http://www.z-table.com), we look up the corresponding z-score for this. This gives us the area to the left of the score, so the heights that are less than 78 inches. This gives us the probability 0.9993.
