According to a study conducted by an organization, the proportion of Americans who were afraid to fly in 2006 was 0.10. A random sample of 1,200 Americans results in 108 indicating that they are afraid to fly. Explain why this is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). C OA. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the probability of obtaining a value equal to or more extreme than the sample proportion is which is not unusual. (Round to four decimal places as needed.) OB. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the sample proportion, very close to 0.10. (Type an integer or a decimal.) OC. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the value of np(1-p) is less than 10. is OD. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the sample size n is more than 5% of the population.

OA. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the probability of obtaining a
value equal to or more extreme than the sample proportion is which is not unusual.
(Round to four decimal places as needed.)
OB. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the sample proportion,
very close to 0.10.
(Type an integer or a decimal.)

OC. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the value of np(1-p) is less
than 10.
D. This is not necessarily evidence that the proportion of Americans who are afraid to fly has decreased below 0.10 because the sample size n is more than
5% of the population.
