Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 392 elementary school teachers and 269 high school teachers. Of the elementary school teachers, 223 said they were very satisfied with their jobs, whereas 126 of the high school teachers were very satisfied with their work. Estimate the difference between the proportion of all elementary school teachers who are satisfied and all high school teachers who are satisfied by calculating a 95% CI.
