When the background music tempo was fast, the mean amount of bar purchases for a sample of 15 patrons in the same restaurant was $20.60 with a standard deviation of $9.90. Assuming equal variances, at a = 0.05, is the true mean higher when the music is slow? Let sample 1 represent the slow tempo and sample 2 represent the fast tempo.
