Assignment 2: Conducting a z-Test<\/span><\/strong><\/p>\n

A researcher predicts that watching a film on institutionalization will change students\u2019 attitudes about chronically mentally ill patients. The researcher randomly selects a class of 36 students, shows them the film, and gives them a questionnaire about their attitudes. The mean score on the questionnaire for these 36 students is 70. The score for people in general on this questionnaire is 75, with a standard deviation of 12. Using the five steps of hypothesis testing and the 5% significance level (i.e. alpha = .05), does showing the film change students\u2019 attitudes towards the chronically mentally ill?<\/span><\/p>\n
