Aprofessor claims that the average score on the first exam of the semester is different than the average score on the second exam. the professor has several large classes, so he selects a random sample of students and compares their scores on the two exams. suppose that data were collected for a random sample of 8 students, where each difference is calculated by subtracting the percentage score from the second exam from the percentage score of the first exam. assume that the populations are normally distributed. the professor uses the alternative hypothesis ha: μd≠0. suppose the test statistic t is computed as t≈0.704, which has 7 degrees of freedom. what range contains the p-value?
