Question 1:A manufacturer receives a shipment of 275 laptop computers of which 24 are defective. Totest the shipment, the quality control engineer randomly, without replacement selects 8computers from the shipment and tests them. The random variable X represents thenumber of non-defective computers in the sample.a) Which probability distribution is applicable for this scenario? Explain why.b) Write the parameter values for the applicable probability distribution.c) What are the mean and standard deviation of the random variable X?d) What is the probability that all selected computer will not have defects?e) Now, let's Y represent the number of defective computers in the sample. What arethe all possible values that Y can take?What are the mean and standard deviation of the random variable Y?What is the probability that at there are at most three defective computers in thesample?f)g)

Given: 24 out of 275 laptop computers are defective. 8 computers are randomly selected. Let X…

After careful research you observe that the number of hackers active on each day is a random variable Bin(3,0.5) distribution. If no hackers are active, the probability of the website failure is 0.15; If one hacker is active the probability of the website failure is 0.3; if two or more hackers are active the probability of the website failure is 0.5. You conclude that the total probability of website failure on a given day is two decimal place). Assuming there is a failure, the probability no hackers are active is (to (to two decimal places).

Choose one: The amount of time a customer spends shopping is a discrete random variable. The amount of time a customer spends shopping is a continuous random variable.
1.) Why does a large value of the F statistics provide evidence against the null hypothesis? 2.) An urn contains 20 colored golf balls: 8 white, 6 red, 4 blue, and 2 yellow.

Choose the correct definition of a random variable from the list below. A random variable is one whose values correspond to a scale with a countable number of values. one that occurs in one of two possible states, labeled success and failure. one that is measured to explain changes in the response variable. one whose values describe the outcome of some chance process. O one whose effect in an experiment cannot be distinguished from the effects of other variables.
