A recent article in the paper claims that business ethics are at an all-time low. Reporting on a recent sample, the paper claims that 44% of all employees believe their company president possesses low ethical standards. Suppose 20 of a company's employees are randomly and independently sampled. Assuming the paper's claim is correct, find the probability that more than eight but fewer than 12 of the 20 sampled believe the company's president possesses low ethical standards. Round to six decimal places.
A) 0.437608
B) 0.285201
C) 0.669843
D) 0.809834

Using the binomial probability formula, the probability that more than eight but fewer than 12 employees believe the president possesses low ethical standards is calculated as P(9 ≤ X ≤ 11) = P(X=9) + P(X=10) + P(X=11), which equals approximately 0.437608.
