Answer:
True : If A and B are independent events, then P(A|B)=P(A) is true.
Step-by-step explanation:
If A and B are independent, P(A and B) = P(A) * P(B)
P(A|B) conditional probability, P(A) given B has already happened
= P(A and B) / P(B)
= P(A)*P(B) / P(B)
= P(A)
Therefore
If A and B are independent events, P(A|B)=P(A) is true.

Answer:
C. If 75% of Americans still favor mandatory testing this year, then there is a 3% chance that poll results will show 72% or fewer with this opinion.
Step-by-step explanation:
Significance level or alpha level is the probability of rejecting the null hypothesis when null hypothesis is true. It is considered as a probability of making a wrong decision. It is a statistical test which determines probability of type I error. If the obtained probability is equal of less than critical probability value then reject the null hypothesis. In this question the sample of 1000 Americans is under test. It is the result of the poll that 75% still favor mandatory testing.
