An instructor thinks that math majors can write and debug computer programs
faster than the math majors. A sample of 18 business majors took an average of
39 minutes and a sample of 12 math majors took an average of 35 minutes. The

is 1.44, is there evidence to support the claim? Assume that the variables are
normally distributed and the population variances are equal. Use α

0.1. Use

the p - value approach.
