Transcribed Image Text:**Title: Understanding Distribution and Percentiles in College Tuition Costs**
**Introduction:**
In this lesson, we will explore the distribution of tuition costs for private nonprofit four-year colleges. Specifically, we will analyze the average cost, the standard deviation, and how to calculate probabilities and percentiles using the normal distribution.
**Problem Statement:**
Private nonprofit four-year colleges charge, on average, $27,552 per year in tuition and fees. The standard deviation is $7,325. Assume the distribution is normal. Let \( X \) be the cost for a randomly selected college. Round all answers to 4 decimal places where possible.
**Tasks:**
a. **Determine the Distribution of Tuition Costs:**
What is the distribution of \( X \)? Express the normal distribution in the form of \( X \sim N(\mu, \sigma) \).
b. **Calculate the Probability:**
Find the probability that a randomly selected private nonprofit four-year college will cost less than $24,769 per year.
c. **Find the 78th Percentile:**
Calculate the 78th percentile for this distribution of tuition costs. Round to the nearest dollar.
**Conclusion:**
Through these exercises, you will gain a practical understanding of how normal distributions are used to model real-world data, like college tuition costs, and how to apply statistical methods to interpret that data.
