A multiple choice calculus test has 5 questions. Each question has five possible choices with only one choice being the correct answer. Let X be the number of questions the student gets correct. (a) List the conditions of the binomial setting, does X follow a binomial distribution? If so, identify n and p. If not, explain why not. (b) What is the probability that a randomly selected student writing the test will get at least 40% on the test?
Assume that random guesses are made for ninemultiple choice questions on an SAT test, so that there are n=9trials, each with probability of success (correct) given by p=0.4Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than 4.
Assume that random guesses are made for nine multiple choice questions on an SAT test, so that there are n=9 trials, each with probability of success (correct) given by p=0.35. Find the indicated probability for the number of correct answers. P(X<4) =
Chris has just received test results from a patient named Cardi who is infected with a mystery disease. The accuracy of the test is as follows:The probability the test will be positive if Cardi is infected is p, and the probability the test will be positive if Cardi is not infected is q. The proportion of the population that is infected is π. The test comes back positive. Chris has no information about the disease and related symptoms. Suppose Chris does not have a true gasp of the base rates. Chris thinks that the base rate is γπ (gamma*pi), with γ is less than or equal to π. This is to make sure that Chris's belief about the prevalance of the mystery disease is no more than 100%. If p=0.95, 1=0.05, π=1, what must be the value of γ if Chris thinks that the probability Cardi has the disease is 0.9? A. 3.57 B. 0.5 C. 1.05 D. 3.214 Please provide explanation
