Some people claim that they can tell the difference between a diet soda and a regular soda in the first sip. a marketing 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". 53 participants correctly identified the soda. what proportion would you estimate would occur if people were randomly guessing which soda was which? do these data provide strong evidence that these people are able to detect the difference between diet and regular soda, in other words, are the results significantly better than just random guessing? use a 95% confidence level. fully explain your workings, and draw any diagrams.
