Two sales scripts, equal spreads: pooled t-test

hypothesis-testingpooled-t-testtwo-sample

Two call-center scripts are compared across reps with similar spreads, so equal variances are assumed. Script A: 20 reps, mean 12 sales, sample standard deviation 4. Script B: 18 reps, mean 15 sales, sample standard deviation 5.

Run a pooled two-sample t-test at the 5% level (two-sided): do the mean sales differ? Report the t-statistic.
