Many college and university students obtain summer jobs. A statistics professor wanted to determine whether students in different degree programs earn different amounts. A random sample of 5 students in the BA, BSc, and BBA programs were asked to report what they earned the previous summer. The results (in $1,000s) are listed here.

Can the professor infer at the 5% significance level that students in different degree programs differ in their summerearnings?
