Do teachers find their work rewarding and satisfying? The article “Work-Related Attitudes” (Psych. Rep., 1991: 443—450) reports the results of a survey of 395 primary school teachers and 266 high school teachers. Of the primary school teachers, 224 said they were very satisfied with their jobs, whereas 126 of the high school teachers were very satisfied with their work. 4.1 Identify the appropriate hypothesis test to be used in this situation, fully describe the sampling distribution of the test statistic, and state all assumptions that have to be satisfied for this test to be used. 4.2 Researchers speculate that the proportion of primary school teachers who are satisfied with their job is greater than the proportion of high school teachers. Test the relevant hypothesis using ? = 0.05
