In the Preview section for Chapter 17, we discussed a study by Loftus and Palmer (1974) examining how different phrasing of questions can influence eyewitness testimony. In the study, students watched a video of an automobile accident and then were questioned about what they had seen. One group of participants was asked to estimate the speed of the cars when they â€ÂÂœsmashed into” each other. Another group of was asked to estimate the speed of the cars when they â€ÂÂœhit” each other. Suppose that the actual speed of the cars was 22 miles per hour.

a. For the 50 people in the â€ÂÂœsmashed-into” group, assume that 32 overestimated the actual speed, 17 underestimated the speed, and 1 was exactly right. Is this result significantly different from what would be expected by chance? Use a two-tailed test with .05.
