Transcribed Image Text:**Educational Content: Analyzing Fat Calorie Distribution**
**Overview:**
The percentage of fat calories that an average person in America consumes daily is typically distributed with a mean value of 36% and a standard deviation of 10%. To explore this distribution, let's analyze this data using statistical methods. We select a random individual and denote \( X \) as the percentage of fat calories.
**Task:**
Determine the maximum percentage value that falls within the lower quartile of the fat calorie distribution. You'll need to round your calculations to two decimal places.
**Process:**
1. **Sketch the Graph:**
- Interpret the normal distribution graph. The graph helps in visualizing the probability distribution of fat calorie percentages ranging from 0 to 70%.
2. **Graphs Explanation:**
- There are four graphs shown, each representing a normal distribution curve centered at 36% (mean value) with varying shaded areas representing different quartile sections. The graphs range from 0% to 70% along the x-axis.
3. **Probability Calculation:**
- Write the probability statement and compute the value by calculating where approximately 25% of people fall in terms of fat calorie consumption.
- You will need to find the cutoff point where the lower 25% of the distribution lies.
**Task Completion:**
- Fill in the statement: "Approximately 25% of people consume ___% of their calories as fat."
- Choose the appropriate graph that reflects the computed quartile percentage.
- Click on the corresponding option to denote your selection of the correct shaded graph.
Remember to round your answers for precision and clarity in analysis.
