- A certain affects virus 0.8% of the population. A test used to detect the virus in a person is positive 88% of the time if the person has the virus (true positive) and 13% of the time if the person does not have the virus (false postive). Fill out the remainder of the following table and use it to answer the two questions below. (enter answer with no commas, i.e. as 1000 not 1,000.) Infected Not Infected Total Positive Test [a] [b] [c] Negative Test [d] [e] [f] Total 800 99,200 100,000 i) Find the probability that a person has the virus given that they have tested positive. (Round your answer to the nearest tenth of a percent and do not include a percent sign.)[g]_______ % ii) Find the probability that a person does not have the virus given that they test negative.

- The head of a computer science department is interested in estimating the proportion of students entering the department who will choose the new computer engineering option. A preliminary sample indicates that the proportion will be around 0.35. Therefore, what size sample should the department head take if she wants to be 95% confident that the estimate is within 0.10 of the true proportion?The averrage gasoline prrice at Chevvron was $3.12 per gallon lastt month. Due to the recent nation-wide gas price drop, the chiief marketing officer of Chevvron believes that there has been a significant reduction in the average gas pricce. In orrder to test hiis belief, he randdomly selected a sample of 36 of Chevvron gas stations and found the average gas price of these stations was $3.06. Assume that the population standard deviation of the population is $0.12, and the significance level (α) is 5%. A. Formmullate the null and the alternative hypotheses: Null: mu ≤ 3.06; Alternative: mu > 3.06 Null: mu = 3.06; Alternative: mu ≠ 3.06 Null: mu ≥ 3.12; Alternative: mu < 3.12 Null: mu = 3.12; Alternative: mu ≠ 3.12 Null: mu ≤ 3.12; Alternative: mu > 3.12 Null: mu ≥ 3.06; Alternative: mu < 3.06 B.

The records show that, when there is no malfunction, the defect rate in the manufacturing process (due to imperfections in the material used) is 1% . When 1.5% or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following. (If necessary, consult a list of formulas.) (a)Find the mean of p , where p is the proportion of defective light bulbs in a sample of 4400 when there is no malfunction. (b)Find the standard deviation of p . (c)Compute an approximation for P≥p0.015 , which is the probability that the service technicians will be called even though the system is functioning properly. Round your answer to four decimal places.
