Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability. In a sample of 900 gas stations, the mean price for regular gasoline at the pump was $2.812 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 55 is drawn from this population. What is the probability that the mean price per gallon is less than $2.809? ..... The probability that the mean price per gallon is less than $2.809 is. (Round to four decimal places as needed.)

**Determine if the finite correction factor should be used. If so, use it in your calculations when you find the probability.** In a sample of 900 gas stations, the mean price for regular gasoline at the pump was $2.812 per gallon and the standard deviation was $0.008 per gallon. A random sample of size 55 is drawn from this population. What is the probability that the mean price per gallon is less than $2.809? The probability that the mean price per gallon is less than $2.809 is _______. (Round to four decimal places as needed.) --- **Instructions for Solving:** 1. **Determine Sample Proportions:** Since the sample size is 55 from a population of 900, consider using the finite correction factor if necessary. 2. **Use Appropriate Statistical Methods:** Compute the probability using the provided mean, standard deviation, and sample size. 3. **Calculate the Z-Score:** Use the standard error and mean to find the Z-score for $2.809. 4. **Find the Probability:** Use the Z-score to determine the probability from standard normal distribution tables or statistical software. --- **Additional Tools:** Buttons available: - "Help Me Solve This" - "View an Example" - "Get More Help" - "Clear All" Users can click "Check Answer" after calculations. (Note: This assumes access to necessary statistical tools or tables for precise calculations.)
