QUESTION 9 Sales records of a hobby shop showed the following number of radio-controlled trucks sold weekly for each of the last 50 weeks. What is the probability of selling either 1 truck or 3 trucks in any given week? Number of Trucks Sold Number of Weeks 20 1 15 2 10 4 1 O P{1 or 3 trucks sold} = 15/50 + 4/50 O P{1 or 3 trucks sold} = 15/50 - 4/50 O P{1 or 3 trucks sold} = 15/50 + 10/ 50+ 4/50 O P{1 or 3 trucks sold} = 15/50 x 4/50 34
QUESTION 7 A virus is known to infect a system with probability 60%. A new antivirus is designed for this threat, and it is tested on a number of systems. It is noticed that the probability that the test detects an infected system is 90%, and the probability that it correctly shows negative when a system is not infected is 80%. Use Baeye's rule to calculate the probability that a system is infected if this test indicates so (a positive test). Enter your answer here as a decimal 0.xx (do not enter more than two decimals, and do not enter less; truncate to the first two decimals and don't round up or down)
Question 38. In a hypothesis test, the Type I error rate is a = 0.10. Suppose we also know that the Type II error rate is 0.20 for this test. What is the probability of making Type I and Type II errors at the same time? Put your answer in percentage. If your answer is "12.34%" then put “12.34" in the blan-
Question 2. A survey found that 62% of callers in the United States complain about the service they receive from a call center if they suspect that the agent who handled the call is foreign.11 Given this context, what is the probability that (state your assumptions) (a) the next three consecutive callers complain about the service provided by a foreign agent? (b) the next two calls produce a complaint, but not the third? (c) two out of the next three calls produce a complaint? (d) none of the next 10 calls produces a complaint?

QUESTION 15 Suppose that in a given town, 60% of the population is under age 40 (event A). It is found that the proportion of residents under age 40 who support mandatory inoculation is 0.72. The proportion of residents over age 40 who support mandatory inoculation is 0.52. Let event B = support mandatory inoculation. Define the term probability by choosing the correct answer below. Probability is the long-run event. Probability is the frequency of an event. Probability is the fraction of times an event occurs in n independent replications of an experiment. Probability is the long-run relative frequency of an event.
