STATS-CE0L14

Suppose that adult male heights in the US are Normally distributed with a mean of $69.5$ inches and a standard deviation of $3$ inches. Suppose an adult male is selected at random.

Use standard normal probability table below to find the probability that the person's height is above $6$ feet. Entry represents shaded area from $-\infty$ to a point.
