ABC manufacturing company producing 6000 steel cylinders in one day by four differentoperators. The Quality Control department would like to randomly check the product in orderto ensure it is meet the specifications. The required sample size, n = 600 and the operationhours for the factory is 12 hours. Illustrate the plan of the rational subgroup if the managerwould like to have the sampling for every 4 hours.

Two different types of injection-moulding machines are used to form plastic parts. A part is considered defective if it has excessive shrinkage or is discolored. Two random samples, each of size 300, are selected, and 15 defective parts are found in the sample from machine 1, and 8 defective parts are found in the sample from machine 2. Construct a 99% lower bound on the difference in the two fractions (p1-p2). Please report your answer to 3 decimals.

John Allen Paulos has pointed out a problem with massive, untargeted wiretaps. To illustrate the problem, he sup-poses that one out of every million Americans has terrorist ties. Furthermore, he supposes that the terrorist profile is 99% accu-rate, so that if a person has terrorist ties, the profile will pick them up 99% of the time, and if the person does not have ter-rorist ties, the profile will accidentally pick them up only 1% of the time. Given that the profile has picked up a person, what is the probability that the person actually has terrorist ties? Dis-cuss how your answer affects your opinion on domestic wire-tapping.

Suppose we observe 84 alcoholics with cirrhosis of theliver, of whom 29 have hepatomas—that is, liver-cell carcinoma.Suppose we know, based on a large sample, that therisk of hepatoma among alcoholics without cirrhosis of theliver is 24%. 5.52 What is the smallest number of hepatomas that wouldhave to be observed among the alcoholics with cirrhosis ofthe liver for the hepatoma experience in this group to differfrom the hepatoma experience among alcoholics withoutcirrhosis of the liver? (Hint: Use a 5% probability of gettinga result at least as extreme to denote differences betweenthe hepatoma experiences of the two groups.)

Suppose that, as Human Resources Manager of a firm with more than 10,000 employees, you are interested in understanding: (i) what fraction of those employees are satisfied with their working conditions and (ii) how many hours your employees spend each evening reading and writing work-related emails. You do not have the budget to survey all employees, so you a sample of 200 employees. The results reveal that: (i) 125 of the sample employees are satisfied with their working conditions and (ii) sample employees spend, on average, 2.2 hours each evening reading and writing work-related emails, with a sample standard deviation of 0.4 hours. 1. Construct and interpret a 95% confidence interval for the proportion (p) of employees who are satisfied with their working conditions. 2. Construct and interpret a 95% confidence interval for the mean number of hours employees spend reading and writing work-related emails each evening.
