Question: Emily flipped a coin to select either her right hand or her left hand, and then asked touch therapists to identify the selected hand. Among 280 trials, the touch therapists were correct 123 times.
q: Given that Emily used a coin toss to select either her right hand or her left hand, what proportion of correct responses would be expected if the touch therapists made random guesses?
Is it asking to find the proportion of right/wrong? the wording is confusing because its making me think of the expected value which = mew, which would just be 140/280. Is the answer 123/280 right? or is it 140/280?
Answer: 123/280 Edit
