**Sample Data for Production Volumes and Total Costs**

Consider the following sample of production volumes and total cost data for a manufacturing operation:

| Production Volume (units) | Total Cost (\$) |
|---------------------------|-----------------|
| 400                       | 3,900           |
| 450                       | 4,500           |
| 550                       | 5,400           |
| 600                       | 6,000           |
| 700                       | 6,600           |
| 750                       | 6,900           |

This data was used to develop an estimated regression equation, \( \hat{y} = 1,121.33 + 7.76x \), relating production volume and cost for a particular manufacturing operation. Use \( \alpha = 0.05 \) to test whether the production volume is significantly related to the total cost. (Use the **F** test.)

### Steps in Hypothesis Testing

1. **State the null and alternative hypotheses.**

    \[
    \begin{aligned}
    & \mathrm{H}_{0}: \beta_{1} \geq 0 \\
    & \mathrm{H}_{a}: \beta_{1} < 0 
    \end{aligned}
    \]

    \[
    \begin{aligned}
    & \mathrm{H}_{0}: \beta_{1} = 0 \\
    & \mathrm{H}_{a}: \beta_{1} \neq 0 
    \end{aligned}
    \]

    \[
    \begin{aligned}
    & \mathrm{H}_{0}: \beta_{1} \leq 0 \\
    & \mathrm{H}_{a}: \beta_{1} > 0 
    \end{aligned}
    \]

2. **Set up the ANOVA table. (Round your p-value to three decimal places and all other values to two decimal places.)**

    | Source of Variation | Sum of Squares | Degrees of Freedom | Mean Square | **F** | p-value |
    |---------------------|----------------|--------------------|-------------|-------|---------|
    | Regression          |                |                    |             |       |         |
    | Error               |                |                    |             |       |         |
    | Total               |                |                    |             |       |         |
