Women's Rights Using your chosen topic, perform the following tasks. Imagine you are a statistician. Write down a research objective, or question, about your chosen topic that you might be interested in learning more about. How would you collect data to study your research objective using cluster sampling? Give a specific example. How would you collect data to study your research objective using stratified sampling? Give a specific example. Which of your two data collection methods would be most efficient for you to perform? Why?

Telephone surveys may use a telephone directory to identify individuals for study. Speculate on the type of household that would be uncovered by using this sampling frame

Match the sampling scheme to an example of that type of sampling.

Suppose that a computer chip company has just shipped 5,000 computer chips to a computer company. Unfortunately, 10 of the chips are defective. (a) Compute the probability that two randomly selected chips are defective using conditional probability 10 (b) The probability that the first randomly selected chip is defective is 5,000 0.002 0.2%.Compute the probability that two randomly selected chips are defective under the assumption of independent events. (a) The probability is (Round to eight decimal places as needed.) (b) The probability is (Round to eight decimal places as needed.) When small samples are taken from large populations without replacement, the assumption of independence does not significantly affect the probability. Based on the results, what does this mean? O A. The probabilities are nearly the same. O B. The probabilities are very different, but the probability found assuming independent events is larger, so it does not matter. OC. The probabilities are exactly the…

Random digit dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differ from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old. Here’s what the Pew survey found about how these people describe their political party affiliation.     Do we reject, or fail to reject, the null hypothesis?
