In 1974, a question can influence eyewitness memory In a question about what they saw. One group was asked, "AL how fast were the cars going when they smashed into each other?" Another group was asked the question except the verb was changed to "hit" in stead of "smashed into." The "smashed into" gre reported significantly higher estimates of speed th the "hit" group. Suppose a researcher repeats this study with a sample of today's college students an obtains the following results. Estimated Speed Smashed into Hit n = 15 n = 15 M = 40.8 M = 34.0 SS = 510 SS = 414 %3D a. Do the results indicate a significantly higher esti- mated speed for the "smashed into" group?
