Historians are interested in the accuracy of eyewitness accounts of traumatic events. One study examined survivors' recall of the sinking of the ship Titanic (Riniolo, Koledin, Drakulic, & Payne, 2003). The researchers reviewed the transcripts of survivors' testimony at governmental hearings (www.titanicinquiry.org) to see whether they testified that the ship was intact or breaking apart during the ship's final plunge (it was in fact breaking apart). To test for eyewitness accuracy,testimony of 20 survivors was examinedto see if there was anequallikelihood of survivors saying the ship was intact or breaking apart.

Question:

1) Write the Null and alternative hypotheses (based on context of study) in symbols and test the assumptions and make a decision (write evidence to support your decision)
