**Question 5**

A population of values has a normal distribution with \( \mu = 123.3 \) and \( \sigma = 6.1 \). You intend to draw a random sample of size \( n = 129 \).

Find the probability that a single randomly selected value is between 122.7 and 123.7.

\[ P(122.7 < X < 123.7) = \_\_\_\_ \]

Find the probability that a sample of size \( n = 129 \) is randomly selected with a mean between 122.7 and 123.7.

\[ P(122.7 < M < 123.7) = \_\_\_\_ \]

Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
