2. A school system has assigned several hundred "chronic and severe underachievers" to an alternative educational experience. To assess the program, a random sample of 135 students has been selected for comparison with all students in the system. In terms of absenteeism (number of days missed per year), what can be said about the success of the program? Assume the researcher is asking, "Are the students in the program absent less than all students in the system?" (7 points) System wide: u = 6.137 Program: X = 3.75; s = 1.11 3. A researcher predicts that showing a certain film will change people's attitudes towards texting and driving. The researcher then randomly selects 100 people, shows them the film and gives them an attitude questionnaire (where a higher score indicates greater attitude against texting and driving). The mean score on the attitude test for these 100 people is 76. The scores for people in general on this test is 75, with a standard deviation of 6. Did the film change people's attitudes towards texting and driving? (7 points)
