10. In 1974, Loftus and Palmer conducted a classic s college students watched a film of an automobile mated speed for the "smashed into" group? Use a demonstrating how the language used to ask a ques- tion can influence eyewitness memory. In the study, accident and then were asked questions about what the cars going when they smashed into each other?" they saw. One group was asked, "About how fast were study Another group was asked the same question excent the verb was changed to "hit" instead of "smashed into." The "smashed into" group reported signifi- cantly higher estimates of speed than the "hit" group. Suppose a researcher repeats this study with a sample of today's college students and obtains the following results. Estimated Speed Smashed into Hit n = 15 n = 15 M = 40.8 М 3 34.0 SS = 510 SS = 414 a. Do the results indicate a significantly higher esti- one-tailed test with a = = .01. b. Compute the estimated value for Cohen's d to measure the size of the effect.
