Gateway 2000, Inc., receives large shipments of microprocessors from Intel Corp. It must try to ensure that the proportion of microprocessors that are defective is small. Suppose Gateway decides to test five microprocessors out of a shipment of thousands of them. Suppose that if at least one of the microprocessors is defective, the shipment is returned.
a. If Intel Corp.'s shipment contains 10% defective microprocessors, calculate the probability the entire shipment will be returned.
b. If Intel and Gateway agree that Intel will not provide more than 5% defective chips, calculate the probability that the entire shipment will be returned even though only 5% are defective.
c. Calculate the probability that the entire shipment will be kept by Gateway even though the shipment has 10% defective microprocessors

What is a probability distribution and its purpose?
Distinguish between discrete and continuous probabilitydistributions. Give an example of each.
What is randomness? Assume you have an Excel worksheet of the dimension, A1:E101. The first row contains data labels. How would you randomize the data file and to select a

Please choose the correct answer and write briefly why.
A property of continuous distributions is that:
a. As with discrete random variables, the probability distribution can be approximated by a smooth curve
b. Probabilities for continuous variables can be approximated using discrete random variables
c. Unlike discret

Question 1:
When is the mean the best measure of central tendency? When is the median the best measure of central tendency? Explain.
Questions 2:
A researcher has determined that the distribution of annual salaries of NBA players is bell-shaped and symmetrical about the mean salary, do you think that introducing Michael

Define probabilitydistributions. Describe two common probabilitydistributions.
Looking for a good original (yet cited) response to this definition. And if you can describe two common ones with an example for each that would be great.

Give an example representing a discreteprobability distribution and another example representing a continuous probability distribution. Explain why your choices are discrete and continuous.
Please provide me an insightful analysis of the question is lengthy in response and include specific examples.

Share 1 real-world binomial distribution situation and 1 real-world Poisson distribution situation. Be sure to explain why each example is defined as binomial or Poisson. How would you characterize the difference between the two types of distributions?

A Tamiami shearing machine is producing 10 percent defective pieces, which is abnormally
high. The quality control engineer has been checking the output by almost continuous
sampling since the abnormal condition began. What is the probability that in a sample of
10 pieces:
a. Exactly 5 w

This project is based on DiscreteDistributions and Continuous Distributions. Question # 7 does not have to be an elaborate study, just something basic, a study that you might conduct at work.
1. What are the characteristics of a normal distribution?
2. Determine the probability or area for the portions of the normal distr
