Out of 10 trials, a receiver got four cards correct. What is her success rate? What is her expected rate of success, assuming she is only guessing? B. Is her higher actual success rate reliable evidence that the receiver has telepathic abilities? Carry out the appropriate hypothesis test. C. Assume another (extremely hypothetical) individual tried to guess the ESP cards 1000 times and was correct 350 of those times. This is very significantly different from the chance rate, yet the proportion of her successes is lower than the individual in part (a). Explain this apparent contradiction.

Question
A. Out of 10 trials, a receiver got four cards correct. What is her success rate? What is her expected rate of success, assuming she is only guessing?
B. Is her higher actual success rate reliable evidence that the receiver has telepathic abilities? Carry out the appropriate hypothesis test.
C. Assume another (extremely hypothetical) individual tried to guess the ESP cards 1000 times and was correct 350 of those times. This is very significantly different from the chance rate, yet the proportion of her successes is lower than the individual in part (a). Explain this apparent contradiction.
Transcribed Image Text:One classical experiment on ESP
(extrasensory perception) tests for the
ability of an individual to show
telepathy-to read the mind of another
individual. This test uses five cards with
different designs, all known to both
participants. In a trial, the "sender" sees
a randomly chosen card and
concentrates on its design. The
"receiver" attempts to guess the identity
of the card. Each of the five cards is
equally likely to be chosen, and only
one card is the correct answer at any
point.
