5) Alcohol consumption is influenced by price and packaging, but what about glassware? Atwood et al. (2012) measured whether the time taken to drink a beer was influenced by the shape of the glass in which it was served. Participants were given a 12 oz. of chilled lager and were told that they should drink it at their own pace while watching a nature documentary. The participants were randomly assigned to receive their beer in either a straight-sided glass or a curved, fluted glass. The data below are the total time in minutes to drink the glass of beer by the 19 women participants in the study. Straight glass: 11.63 10.37 17.89 6.96 20.40 20.64 9.26 18.11 10.33 23.54 Curved glass: 7.46 9.28 8.90 6.73 8.25 6.16 13.09 2.10 6.37 a. Show the data in a graph. What trend is suggested? Comment on other differences between the frequency distributions of the two samples. b. Test whether the mean total time to drink the beer differs depending on beer glass shape.
