14.19 An increasing number of public school districts are utilizing the iPad as a teaching tool. Suppose Calandlyceum, a high school in Amsterdam, recently distributed 47 iPads to the students and teachers in two humanities classes, with expectations that in time all 1,100 students will be provided with iPads (Hu 2011). Educators are divided on their opinion as to the academic benefit of iPads. Much research is needed to determine if iPads are an enhancement to learning or just another technological fad. Assume that a random sample of high school teachers

(math, history, science, and language teachers) were surveyed and asked, Do you think the iPad will enhance learning? Determine if there is an association between the subject taught and the response to this question.
