Question
### Problem Statement

A company manufactures batteries in batches of 6 and there is a 3% rate of defects. Find the mean number of defects per batch. Round to the nearest tenth as needed.

### Options

- **A.** 18 defects
- **B.** 5.8 defects
- **C.** 1.8 defects
- **D.** 0.2 defects

**Click to select your answer.**

### Explanation

To calculate the mean number of defects per batch, you need to multiply the total number of batteries in a batch by the defect rate:

\[
\text{Mean number of defects} = \text{Total number of batteries} \times \text{Defect rate}
\]

In this problem:

- Total number of batteries per batch = 6
- Defect rate = 3% or 0.03

\[
\text{Mean number of defects} = 6 \times 0.03 = 0.18
\]

Rounding 0.18 to the nearest tenth gives 0.2.

Therefore, the correct answer is **D. 0.2 defects**.
