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. Assume all assumptions are met for this hypothesis test. Calculate the test statistic for this hypothesis test? (round to four decimal space) a. 0.7333 b. Cannot calculate with given information. c. 0.7968 d,0.7000
