show all the work and calculation step by step plz ,,1. In 1974, Lotus and Palmer conducted a classic study demonstrating how the language used to ask a question can influence eyewitness memory. In the study, college students watched a filmed of an automobile accident and then were asked about what they saw. One group was asked, questions what they saw. One group was asked, "About how fast were the cars going when they smashed into each other?" Another group was asked the same question expect the verb was changed to hit" instead of smashed into" group reported significantly 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 ,n = 15, M = 40. 8, SS = 510 ,,Hit,n = 15, M = 34. 0, SS = 414,,2. Harris, Schoen, and Hensley (1992) conducted a research study showing how cultural experience can influence memory. They presented participants with two different versions of stories. One version contained facts or elements that were consistent with a U.S. culture and the second version contained material consistent with a Mexican culture. The results showed that the participants tended to make memory errors for the information that was not consistent with their own culture. Specifically, participants from Mexico either forgot or distorted information that was unique to U.S. culture, and participants from the United States forgot or distorted information that was unique to Mexican culture. The following data represent results similar to those obtained by Harris, Schoen, and Hensley. Is there a significant difference between the two groups? Use a two-tailed test with ? = .05.,Number of Errors Recalling the Mexican Story,,Participants from Mexico ,n = 20, M = 4.1, SS = 180 ,,Participants from the United States, n = 20, M = 6.9, SS = 200,,,3. Steven Schmidt (1994) conducted a series of experiments examine the effects of humor on memory. In one studied, participants were given a mix of humorous and nonhumorous sentences and significantly more humorous and sentences were recalled. However, Schmidt argued that the humorous sentences were not necessarily easier to remember, they were simply preferred when participants had a choice between the two types of sentence. To test this argument, he switched to an independent-measures design in which one group got a set of exclusively humorous sentences and another group got a set of exclusively nonhumorous sentences. The following data are similar to the results from the independent-measure study.,,Humorous sentences,4-5-2-4,6-7-6-6,2-5-4-3,3-3-5-3,,Nonhumorous sentences,6-3-5-3,3-4-2-6,4-3-4-4,5-2-6-4,,
