Chapter 01.3 Exercise Question 17

1.3.17

Tasting tea

A famous (in statistical circles) study involves a woman who claimed to be able to tell whether tea or milk was poured first into a cup. She was presented with eight cups containing a mixture of tea and milk, and she correctly identified which had been poured first for all eight cups. Is she doing better than if she were just guessing?

Use an applet to generate the null distribution of sample proportion of correct identifications and use it to determine the standardized statistic.(Round answer to 2 decimal places, e.g. 52.75)
