**Exhibit 10-30**

In order to determine whether or not there is a significant difference between the hourly wages of workers at Ford and Ferrari, the following data have been accumulated.

**Ford**
- \( n_1 = 50 \)
- \( \bar{x}_1 = \$20.50 \)
- \( \sigma_1 = \$2.50 \)

**Ferrari**
- \( n_2 = 70 \)
- \( \bar{x}_2 = \$10.25 \)
- \( \sigma_2 = \$2.00 \)

Refer to Exhibit 10-30. What is the formula we would use to find the degrees of freedom in this problem?

- ❏ n1-n2-1
- ❏ n1+n2-1
- ❏ None, this is not a T-distribution problem
- ❏ n-1
