The rule of the z-score is

μ is the mean
σ is the standard deviation
Since the average of the height of an adult male is 70 inches, then

Since the standard deviation is 3 inches, then

We need to find the percentage of the height of the adult males between 65 and 75 inches, then

We will find the z-score of them


We will use the given table to find their areas

We will subtract both values to find the answer
[tex]\begin{gathered} P(65We will change it to percent, then[tex]\begin{gathered} P(65
The answer is 90.5%
