Question

**Understanding Sample Means: Educational Exercise**

This exercise helps students calculate the mean of a sample set, which is an essential statistic in understanding data trends. Here's the task:

---

**Task Description:**

The state test scores for 12 randomly selected high school seniors are provided. The scores are:

- 1421, 1227, 986
- 692, 720, 831
- 730, 748, 546
- 630, 1448, 946

Assume the population from which these scores are drawn is normally distributed.

**Instructions:**

(a) Find the sample mean (denoted as $\bar{x}$).

- Once calculated, round your answer to one decimal place as needed.

**Input Method:**

Enter your answer in the answer box provided and then click "Check Answer" to verify your solution.

---

**Calculation Guidance:**
