Taste test. Some people claim that they can tell the difference between a diet soda and a regular soda in the first sip. A researcher wanting to test this claim randomly sampled 80 such people. He then filled 80 plain white cups with soda, half diet and half regular through random assignment, and asked each person to take one sip from their cup and identify the soda as diet or regular. 48 participants correctly identified the soda. If the research question is "Are these people any worse or better than random at determining whether the soda is diet or regular?" then what is the corresponding p-value?
