A population of values has a normal distribution with [tex]\mu = 213[/tex] and [tex]\sigma = 39.1[/tex]. What is the probability that a single randomly selected value is greater than 208? Write your answer as a decimal to the nearest 3 decimal places.

Answer :

Final answer:

The probability that a single randomly selected value is greater than 208 in a normal distribution can be found using the z-score formula. The probability in this case is approximately 0.449.

Explanation:

To find the probability that a single randomly selected value is greater than 208 in a population with a normal distribution, we can use the z-score formula.

z = (x - μ) / σ

Plugging in the values, we get z = (208 - 213) / 39.1 = -0.128.

Using a z-table, we find that the probability corresponding to a z-score of -0.128 is approximately 0.449. Therefore, the probability that a single randomly selected value is greater than 208 is approximately 0.449.
