- A social scientist gathers a carefully chosen group of 20 people whom she is selected to represent a broad cross section of the multiple of the population in New York City. She interviews them in depth for a study that she is doing regarding race relations in the city. Is there a probability sample? Explain your answer.Diet Dr.Pepper is going old school and putting a "Free DP" notification under 10% of their 20-oz bottle caps. If I purchase a 6-pack of 20-oz bottles, what is the probability that I win at least two free drpeppers?In an article that appears on a website,† Carlton Gunn, a public defender in Seattle, Washington, wrote about how he uses statistics in his work as an attorney. He states the following. I personally have used statistics in trying to challenge the reliability of drug testing results. Suppose the chance of a mistake in the taking and processing of a urine sample for a drug test is just 1 in 100. And your client has a "dirty" (i.e., positive) test result. Only a 1 in 100 chance that it could be wrong? Not necessarily. If the vast majority of all tests given—say 99 in 100—are truly clean, then you get one false dirty and one true dirty in every 100 tests, so that half of the dirty tests are false. Define the following events as given below. TD = event that the test result is dirty TC = event that the test result is clean D = event that the person tested is actually dirty C = event that the person tested is actually clean (a) Using the information in the quote, compute the following…

So why do different insurance companies charge different amounts for the same coverage? The policy total is determined by the population of former and current policy holders for each company. A different pool of policy holders produces different results. However, the commonalities are often similar. The law of large numbers gives an insurance company a fairly reliable indication of what each insurance policy will cost the company, on average. Some policy holders will go for years without making a claim. Other policy holders will cut into the bottom line profit with costly claims which are not always recouped as policy holders sometimes change insurance providers. After natural disasters, a large volume of claims are filed which also must be planned for when setting policy rates. Although natural disasters and large claims are not typically common, the…Do a mini report on the following topic: Conditional probability
