Hungry? Researchers investigated how the size of abowl affects how much ice cream people tend to scoopwhen serving themselves.14 At an “ice cream social,”people were randomly given either a 17 oz or a 34 ozbowl (both large enough that they would not be filledto capacity). They were then invited to scoop as muchice cream as they liked. Did the bowl size change theselected portion size? Here are the summaries: Test an appropriate hypothesis and state your conclu-sions. Assume any assumptions and conditions that you cannot test are sufficiently satisfied to proceed. Small Bowl Large Bowln 26 n 22y 5.07 oz y 6.58 ozs 1.84 oz s 2.91 oz
