Textbook Problem

**Critical Thinking** Lorraine was in a hum when she computed a confidence interval for µ. Because *a* was not known, she used a Student's *t* distribution. However, she accidentally used degrees of freedom *n* instead of *n* - 1, Was her confidence interval longer or shorter than one found using the correct degrees of freedom *n* - 1 ? Explain.

To determine

Whether the Lorraine confidence interval was longer or shorter than one found using the correct degrees of freedom *n*-1.

Explanation

As the degrees of freedom increases, the critical value decreases. Hence, the confidence interval is shorter than one found using the correct degrees of freedom *n*-1...
