Telepathic or just pathetic?Analysis

• Listen carefully as the cards that were
  transmitted are read out in order
• Mark each one as correct (or not) and add up how
  many transmissions you correctly received

39
Telepathic or just pathetic?Analysis

• Based on samples of 30 from a population with p
  0.2
• Using the binomial distribution
• Setting limits for sample proportions based on
  the population proportion

Telepathic or just pathetic?Conclusion

• Are you telepathic? Explain your answer using
  statistics.
• Do you have any concerns about the design of the
  experiment?
