content area top Part 1 Researchers investigated how the size of a drinking glass affects how much soda people tend to pour themselves. People were randomly given either a 17 oz or a 25 oz glass, and were invited to pour as much soda as they liked. Did the glass size change the selected portion size? The summaries are shown to the right. Assume any assumptions and conditions are satisfied. Complete parts a through c. Use alphaequals0.05.

Upper H 0: The mean for the smaller glass is the same as the mean for the larger glass; that is, mu 1minusmu 2 equals 0, where mu 1 is the population mean of the small glass soda volumes and mu 2 is the population mean of the large glass soda volumes. Upper H Subscript Upper A: The mean for the smaller glass is different from the mean for the larger glass; that is, mu 1minusmu 2 not equals 0, where mu 1 is the population mean of the small
