A statistics class participated in an online mock juror experiment examining the influence of eyewitness testimony credibility on guilt ratings where students were randomly assigned to read trial testimony that either included credible eyewitness testimony, discredited eyewitness testimony, or no eyewitness testimony. Following the presentation of the evidence, ratings of guilt were taken from each student on a scale of 1 - 7 with higher ratings indicating higher likelihood of guilt. The data are shown below: Eyewitness No Eyewitness Discredited Eyewitness n1 = 68 n2 = 57 n3 = 63 * = 321/68 = 4.72 * = 251/57 = 4.40 * = 242/63 = 3.84 S, = 1.78 S, = 2.00 S, = 2.00 Question 35 (1 point) What is the observed test statistic (assuming all assumptions have been met)? 4.77 3.23 6.70 13.36 MacBook Air DII DD F3 F4 F5 F6 F7 F8 F9 F10 # % & 3 A 5 6 7 8 9 O E R T Y U O PQuestion 35 (1 point) What is the observed test statistic (assuming all assumptions have been met)? 4.77 3.23 6.70 13.36 1.92 Question 36 (1 point) What is your critical value and conclusion for the study above? 4.65; there are no significant differences in the guilt ratings provided by mock MacBook Air 20 988 DII DD F3 F4 F5 F6 F7 F8 F9 $ % & ** 4 5 7 8 O R T Y U O FQuestion 36 (1 point) What is your critical value and conclusion for the study above? 4.65; there are no significant differences in the guilt ratings provided by mock jurors as a function of the type of eyewitness evidence presented during trial 3.04; there are significant differences in the guilt ratings provided by mock jurors as a function of the type of eyewitness evidence presented during trial 2.62; there are significant differences in the guilt ratings provided by mock jurors as a function of the type of eyewitness evidence presented during trial 3.01; there are no significant differences in the guilt ratings provided by mock jurors as a function of the type of eyewitness evidence presented during trial 4.71; there are significant differences in the guilt ratings provided by mock jurors as a function of the type of eyewitness evidence presented during trial The following four questions refer to the study below.
