#### Understanding Mean and Standard Deviation in Sample Data

In the exercise below, you’re guided on how to round the mean and standard deviation for different sample sizes. Pay attention to the rounding instructions provided.

---

**a.** \( n = 60 \)  
(Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)

- **Mean**: 45.60
- **Standard Deviation**: 4.2700

---

**c.** \( n = 28 \)  
(Round your mean value to 2 decimal places and standard deviation to 4 decimal places.)

- **Mean**: 26.60
- **Standard Deviation**: (No value provided)

---

Note the following:

1. **Mean**: This represents the average value of your data set. The mean is calculated by summing all the values in the sample and dividing it by the number of values.

2. **Standard Deviation**: This measures the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Remember, precise rounding of mean and standard deviation is crucial for maintaining the accuracy of your statistical analysis. In these examples, ensure the mean is rounded to 2 decimal places and the standard deviation to 4 decimal places as instructed. 

Understanding and calculating these fundamental statistical measures accurately forms the backbone of data analysis, making interpretations of data sets more reliable and meaningful.
