Based on a survey, assume that 37% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Identify the values of n, x, p, and q.
Homework Answers
X ~ Bin ( n , p)
n = 5 , x = 2 , p = 0.37 , q = ( 1 - 0.37) = 0.63
Using binomial distribution
P(X) = nCx px qn-x
P(X = 2) = 5C2 * 0.372 * 0.633
0.3423

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 59 tablets, then accept th batch if there is only one or none that doesn't meet the required specifications. If one shipment of 4000 aspirin tablets actually has a 4% rate of defects, what probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected? The probability that this whole shipment will...

Business Weekly conducted a survey of graduates from 30 top MBA programs. On the basis of the survey, assume the mean annual salary for graduates 10 years after graduation is 131000 dollars. Assume the standard deviation is 36000 dollars. Suppose you take a simple random sample of 73 graduates. Do not use probability tables to find the probabilities below as they may not be accurate enough. Find the probability that a single randomly selected salary is at least 126000 dollars....

In analyzing hits by certain bombs in a war, an area was partitioned into 582 regions, each with an area of 0.85 km2. A total of 525 bombs hit the combined area of 582 regions. Assume that we want to find the probability that a randomly selected region had exactly two hits. In applying the Poisson probability distribution formula, P ( x ) = λ x ∙ e − λ x !, identify the values of λ , x , a...
