The Gallup website reported results from a recent poll of American teachers and asked if they opposed the idea of teachers and staff carrying guns in schools. Let's assume that this poll involved a random sample of 120 American teachers and found that 88 of these teachers opposed the idea of teachers and staff carrying guns in schools. Based on this sample, is there evidence that the true population proportion of American teachers that are opposed to the idea of teachers and staff carrying guns in school is more than 70 % ? Use a level of significance of 0.05. What is the null and alternative hypothesis for this hypothesis test? a. H: p=0.70 H:p 0.70 b. H : p=0.70 H:p>0.70 c. H : p=0.70 H:p<0.70 d. H:p>0.70 H: p=0.70
