Check the ones I answered to make sure they are right and find P-Value

Extracted text: 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 a= 0.05. Small Glass Large Glass - 29 n 29 y 4.83 oz 6.55 oz 1.83 oz 3.05 oz a) Write appropriate hypotheses. Ho: : The mean for the smaller glass is the same as the mean for the larger glass; that is, µ, - H2 = 0, where is the population mean of the small glass soda volumes and u, is the population mean of the large glass soda volumes. : The mean for the smaller glass is different from the mean for the larger glass; that is, µ, - H, + 0, where u, is the population mean of the small glass soda volumes and µ, is the population mean of the HA large glass soda volumes. b) Find t and the P-value for these results. t= - 2.604 (Round to three decimal places as needed.) P-value = (Round to four decimal places as needed.) c) State your conclusion in context. |Reject Hn. The data provide sufficient evidence to conclude that the mean for the smaller glass is | different from| the mean for the larger glass.
