Title: Understanding Data Sets

---

**Give an example of a data set with:**

- \( N = 4 \)
- \( \mu = 7.1 \)
- \( \sigma = 0 \)

---

This problem asks you to create a data set consisting of four values (N=4) where the mean (\(\mu\)) is 7.1 and the standard deviation (\(\sigma\)) is 0. 

**Explanation:**

- A mean (\(\mu\)) of 7.1 indicates that the average of all numbers in the data set should be 7.1.
- A standard deviation (\(\sigma\)) of 0 implies that all values in the data set are identical since there is no spread or variation in the data.

**Forming the Data Set:**

Given these conditions, the data set should contain four identical numbers, each being 7.1:

\[ \{7.1, 7.1, 7.1, 7.1\} \]

This satisfies both the given mean and standard deviation, as the average is 7.1 and there is no deviation from this value.

Expert Solution
Step 1

We are given

      N = 4

      μ = 7.1

      σ = 0

The standard deviation being zero indicated that there is no or zero variation in the data. Implying that all the observations are the same or equal.
