**Problem Statement:** The lengths of pregnancies in a small rural village are normally distributed with a mean of 264 days and a standard deviation of 17 days. A distribution of values is normal with a mean of 264 and a standard deviation of 17. What percentage of pregnancies last beyond 279 days? \[ P(X > 279 \text{ days}) = \_\_\_\_ \% \] Enter your answer as a percent accurate to 1 decimal place (do not enter the "%" sign). Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. **Instructions:** 1. Calculate the z-score for 279 days using the given mean and standard deviation. 2. Find the probability using a standard normal distribution table or a calculator. 3. Express the probability as a percentage rounded to 1 decimal place. **Interactive Element:** [Next Question]
