Question

### Understanding Normal Distribution of Prices for HD Televisions

The graph illustrates a normal distribution for the prices paid for a particular model of HD television. The mean price paid is $1400, and the standard deviation is $75.

#### Graph Description:

The graph features a bell curve representing the normal distribution of prices. The x-axis is labeled "Distribution of Prices," with price increments marked as follows:
- 1175
- 1250
- 1325
- 1400
- 1475
- 1550
- 1625

These increments represent the prices at one standard deviation intervals away from the mean price of $1400.

#### Questions and Exercises:

1. **What is the approximate percentage of buyers who paid between $1400 and $1625?**
- [ ]

2. **What is the approximate percentage of buyers who paid between $1400 and $1550?**
- [ ]

3. **What is the approximate percentage of buyers who paid more than $1550?**
- [ ]

4. **What is the approximate percentage of buyers who paid less than $1175?**
- [ ]

5. **What is the approximate percentage of buyers who paid between $1325 and $1475?**
- [ ]

6. **What is the approximate percentage of buyers who paid between $1400 and $1475?**
- [ ]

These questions are designed to help you understand the distribution of data in a normal distribution curve centered around a mean with a specific standard deviation. By knowing the mean and standard deviation, you can calculate the percentage of data points lying within certain ranges of the distribution. Use the properties of the normal distribution to estimate these percentages.
