9. Vending Machine. A vending machine dispenses coffee into an 8-ounce cup. The amount of coffee dispensed into the cup is normally distributed with a standard deviation of 0.03 ounces. You can allow the cup to overfill 1% of the time. What amount should you set as the mean amount of coffee to be dispensed? Draw, shade and label a normal curve to illustrate your results.

Question
**Vending Machine Problem**

A vending machine dispenses coffee into an 8-ounce cup. The amount of coffee dispensed into the cup is normally distributed with a standard deviation of 0.03 ounces. You can allow the cup to overfill 1% of the time. What amount should you set as the mean amount of coffee to be dispensed? 

**Task:**

- Draw, shade, and label a normal curve to illustrate your results.

**Explanation of the Graph:**

To solve this, you would typically use a normal distribution curve. The horizontal axis represents the amount of coffee in ounces, and the curve shows the probability of dispensing that amount.

- The peak of the curve is the mean amount of coffee to be dispensed.
- The curve is symmetrical, with most of the data falling near the mean.
- At 1% overfill, you would find the point on the curve such that 1% of the area under the curve lies to the right of this point. This point is typically found using a Z-table or statistical software.
- Shade the area to the right of this point to represent overfill.

This visual representation helps in understanding how often the vending machine overfills the cup based on the set mean and standard deviation.
