Sharon claims that 90% of students can identify the smell of a skunk. She carries out a study to test this theory. She selects a random sample of 100 students and asks them each to take a whiff from a bag that is filled with skunk smell. She finds that 84 are able to correctly identify the smell as that of a skunk. She would like to know if these data provide convincing evidence that less than 90% of students can identify the smell of a skunk. Use a = 0.05. Calculate the P- Value
