Constructed Response Question 2 A teacher claims that their students are missing more than 10% of the assignments for the third quarter. We take a random sample of 25 students and see that 12% of their assignments are missing. Using a = 0.05, can we support the teacher's claim? Perform a normal distribution rejection region hypothesis test for proportions. Show all seven steps.
