Chapter 17, Problem 78E

Thirsty? Researchers randomly assigned participants either a tall, thin “highball” glass or a short, wide “tumbler,” each of which held 355 ml. Participants were asked to pour a shot (1.5 oz = 44.3 ml) into their glass. Did the shape of the glass make a difference in how much liquid they poured? Here are the summaries:

Highball Tumbler
n 99 n 99
ӯ 42.2 ml ӯ 60.9 ml
s 16.2 ml s 17.9 ml
