A market research company has approached you about the possibility of using its services to help you decide whether to launch a new product. According to its customer portfolio, it has correctly predicted a favorable market for its clients' products 18 out of the last 20 times. It has also correctly predicted an unfavorable market for its clients' products 9 out of 12 times. Without this research company's help, you have estimated the probability of a favorable market at 0.58. Calculate the posterior probabilities, using the track record of the research firm.

A diagnostic test for disease X correctly identifies the disease 90% of the time. Flase positives occur 12%. It is estimated that 5.36% of the population suffers from disease X. Suppose the test is applied to a random individual from the population. What is the percentage chance that given a negative result, the person does not have disease X? What is the percentage chance that, the person will be misclassified?
What is the name of the most appropriate statistical / analysis to use to answer the question for the given study. Be specific.
You’ve just begun your surgical residency at Sacred Heart hospital. Today you’ve been assigned thesame surgery (Lobotomy) six times. Bringing back fond memories of your favorite statistic class incollege you begin to remember that the probability of success for this type of surgery is 0.70. Being aprofessional, you know that the outcome of any one surgery won’t affect your ability to perform thenext. Given that you’re operating six times today, what is the probability that only four of the six ofthe surgeries are a success?
Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
