Researchers were interested if the shape of the drinking glass affected how quickly beer was consumed. They gave one group of subjects a straight glass of beer and another group of subjects a curved (flute) glass with the same volume of beer. Subjects were unaware of the reason for the testing to avoid bias. Then the researchers measured how many minutes it took for individuals to consume each beer. They wanted to see if glass shape affected the mean drinking time to consume the beer. Perform a Welch's t-test to analyze this data. beerglass <- read.csv(url("http://whitlockschluter.zoology.ubc.ca/wp- content/data/chapter 12/chap12q32BeerGlassShape.csv")) beerglass Due to how the table is formatted, copy and paste the following code for Welch's t- test:
