Parapsychology Studies EXPLORAT 2.3 Statistician Jessica Uts has conducted an extensive analysis of Ganzfeld studies that have investigated psychic functioning, Ganzfeld studles involve a "sender and a receiver. Two people are placed in separate acoustically shielded rooms. The sender looks at a Target image on a television screen (which may be a static photograph or a short movle segment playing repeatedly) and attempts to transmit information about the target to the recelver The recelver is then shown four possible cholces of targets, one of which is the correct target and the other three are "decoys. The recelver must choose the one he or she thinks best matches the description transmitted bythe sender, Ifthe correct target is chosen by the recelver, the session is a "hit Otherwise, it is a miss. Utts reported that her analysis considered a total of 2,124 sessions and found a total of 709 hits (Utts, 2010). 1. If the subjects in these studies have no psychic ability, what would be the long-run proba- bility that the receiver would identify the correct target? If there is no ability, then in long run the probability of correct hit 2. State the appropriate null and alternative hypotheses for testing whether the data pro- vide strong evidence of psychic ability. Be sure to define the parameter clearly in your hypotheses The null; The probability of hit-0.25 Alt; The brobability of hit 0.25 Calculate the proportion of "hits" (successful transmissions of the target image) among the 2,124 sessions that the researcher analyzed. Is this proportion larger than the null hypothesized value for the probability of a successful transmission? 709/2124-0.3338 3. 4. Use a simulation-based method to determine an approximate p-value for testing the hypotheses stated in #2). To enter speci formatting, us Windows and Mac. 5. Confirm that the validity conditions for a theory-based method are satisfied. Then use the theory-based method to calculate a standardized statistic and p-value for testing the hypotheses stated in #2), 6. Based on the p-values and standardized statistic, would you characterize the evidence against the null hypothesis as weak, moderate, strong, or very strong? Explain.
