1. Alena knows that her morning cup of coffee is most definitely a discretionary
expense. She pays $2.75 for a 9-oz cup and was wondering if that is a
typical price. On Monday, she asked six of her coworkers what they paid
for a 9-oz cup of coffee. Their costs per cup were $2.85, $2.15, $1.95, $3.00,
$2.05, and $2.40. How can Alena compare her expense with those of her
coworkers?
