Suppose we are testing people to see whether the rate of use of seat belts has changed
Question:
Suppose we are testing people to see whether the rate of use of seat belts has changed from a previous value of 88%. Suppose that in our random sample of 500 people we see that 450 have the seat belt fastened. Which of the following figures has the correct p value for testing the hypothesis that the proportion who use seat belts has changed? Explain your choice.

I have been tutoring and serving as a mentor for numerous students (from high schoolers to university/medical students) over the past 3 to 4 years. I personally look at tutoring as a two-way street where I expect students to learn a lot from me but also for me to learn a great deal about how to communicate. I have tutored extensively in test preps (MCAT/SATs), as well as math (algebra) and sciences (chemistry/biology/physics). Having majored in biochemistry in my undergraduate (Cornell University), I know that there may be difficult concepts and I am looking forward to working with you to grasp these concepts.
