Question
**Understanding Sampling Error**

In this scenario, we are presented with a population that has a mean (average) of 121. We take a random sample of 8 items from this population, and the resulting sample values are as follows:

- 116
- 122
- 98
- 145
- 148
- 110
- 141
- 144

**Objective:**
The task is to calculate the sampling error for this sample. The sampling error is the difference between the sample mean and the population mean. 

**Steps to Calculate Sampling Error:**

1. **Calculate the Sample Mean:**
   - Add all the sample values together.
   - Divide the total by the number of items in the sample (8 in this case).

2. **Determine the Sampling Error:**
   - Subtract the population mean (121) from the sample mean found in step 1.

**Note:** The answer should be simplified and should not be rounded.
