A researcher predicts that watching a film on institutionalization will change students\u2019 attitudes about chronically mentally ill patients.

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 <\/p>\n

\nCalculate the obtained z. Do you reject or fail to reject the null hypothesis
\nState in words what you have found.<\/p>\n
