How might you use probability to understand what percent of the emails sitting in your spam folder are genuinely spam emails?

- Hi, please thank you A study is conducted to assess the impact of caffeine consumption, smoking, alcohol consumption, and physical activity on the risk of cardiovascular disease. Suppose that 40% of participants consume caffeine and smoke. If 8 participants are evaluated, what is the probability that: Exactly half of them consume caffeine and smoke?Recall the use of data from the National Health Survey to estimate behaviors such as alcohol consumption, cigarette smoking, and hours of sleep for all U.S. adults. In the 2005-2007 report, they estimated that 30% of all current smokers started smoking before the age of 16. Suppose that we randomly select 100 U.S. adults who are smokers and find that 25% of this sample started smoking before the age of 16. Is this much error surprising? Find the probability that a sample proportion will be an over- or underestimate of the parameter by more than 5%.Organizing a fundraiser is a tough job, but calculating probabilities can improve your chances of getting pledges and donations. Let's look at the expected values, or empirical data. From the previous years’ donor lists, you have probability information about: the types of donors whether they pledged on the phone whether they actually donated The types of donors on your calling list and their probabilities are: gave last year (L), 60% gave in the past but not last year (P), 20% new contacts (N), 20% You can also make these assumptions based on information about past and prospective donors: Of last year's donors, 50% will pledge again and 80% of them will actually send the donation. Of past donors, 40% will pledge again and 60% of them will actually donate. Of new contacts, 10% pledge and 50% of them actually donate. The average amount pledged to your organization is: $280 from those who gave last year $160 from those who gave in the past but not last year $145 from new contacts…
- Spinning a coin, unlike tossing it, may not give heads and tails equal probabilities. I spun a penny 275 times and got 122 heads. We wish to find how significant is this evidence against equal probabilities. a. What is the sample proportion of heads? Round to 3 decimal places. b. Heads do not make up half of the sample. Is this sample evidence that the probabilities of heads and tails are different? Take p to be the probability of getting heads in a spin of a penny. Which hypotheses do we want to test? O Họ: p = 0.5 Họ: p > 0.5 O Ho: p = 0.5 Ho: p < 0.5 O Ho: p = 0.5 Ho: p 0.5 O Ho: p 0.5 Ho: p = 0.5 c. Compute the z test statistic.

- Discuss the implications of nonresponse error; consider this to be questionnaires that are sent to a sample and are not returned. For example say 400 people are selected for a probability sample but only 200 complete and return the survey. Also discuss ways to deal with nonresponse error and to discover whether or not it is a problem. A critical issue here is how to go about proving that the sample results that are actually obtained are representative of the population. What can be done to corroborate this?Virtually any process can be improved by use of statistics, including the law. A much publicized case that involved a debate about probability was the Collins case, which began in 1964. An incident of purse snatching in the Los Angeles area led to the arrest of Michael and Janet Collins. At their trial, an "expert" presented the probabilities listed in table below on characteristics possessed by a couple seen running from the crime scene: Characteristics Probability Man with beard 1/10 Blond woman 1/4 1/10 Yellow car Woman with ponytail Man with moustache Interracial couple 1/10 1/3 1/1000 The chance that a couple had all these characteristics together is 1 in 12 million. Because the Collinses had these characteristics, the Collinses must be guilty. Do yo see any problem with this line of reasoning? Hint: The question of interest is not "what is the probability of finding a couple with these characteristics?" because one such couple has been found (the Collinses), the question is "what…Hello. Please answer the attached Probability question correctly by using Bayes' Theorem. The correct answer is 11.5%, however, I do not know how this answer is obtained if you can show me, I will give a thumbs up. Thank you.
