A professor gives a multiple choice exam where each question has five choices. The professor decides not to count a question against students if the class as a whole does significantly worse on the question than they would have done simply by guessing. In other words, the teacher tests H_0: p=0.20versus H_ ext{a}: p<0.20 for each question, where p is the proportion of students who would correctly answer the question. Suppose that 14 of 100 students correctly answer a particular question. Assuming that the conditions for inference have been met, calculate the test statistic for the professor's significance test.

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
