Suppose that height is normally distributed with a mean of 68 inches and a standard deviation of 4 inches. How many inches tall are the tallest 3% of people?

Answer :

Final answer:

The tallest 3% of people have a height of approximately 75.52 inches.

Explanation:

To find the height of the tallest 3% of people, we need to find the z-score associated with a cumulative probability of 0.97. Using the standard normal distribution table, we find that the z-score is approximately 1.8808. Next, we use the z-score formula to calculate the corresponding height:

x = mean + (z * standard deviation)

Plugging in the values, we get:

x = 68 + (1.8808 * 4) = 75.5232 inches

Therefore, the tallest 3% of people have a height of approximately 75.52 inches.
