05. Suppose we wish to study the relationship between religious affiliation and geographical region. Two groups of people are chosen at random, one from the east coast and one from the- west coast of the United States and each person is classified as Protestant, Catholic, or Jewish. The observed frequencies are presented in the following table. Protestant Catholic Jewish East coast West coast 215 136 182 203 154 110 Test to see if religious faith is independent of the region where one lives. For this test, specify the null and the alternate hypotheses that are being tested, report the X² test statistic and the critical value you are using to conduct the test, and clearly state the conclusion of the test in the context of the problem (use =0.05).

A machine produces parts that are either good (80%), slightly defective (10%), or obviously defective (10%). Produced parts get passed through an automatic inspection machine, which is able to detect any part that is obviously defective and discard it. What is the quality of the parts that make it through the inspection machine and get shipped?
Nidec Sankyo Vietnam Corporation, founded in 2005, over 14 years of operation, Nidec Sankyo Vietnam Corporation has become a supplier for many major companies such as Canon, Mitsubishi, Toto, Brother, Kyocera, etc. Some of the company's outstanding products are motors and drives, card readers, plastic injection processing, music boxes, JIG, hot stamping molds, steel molds, metal molds, electronic components, computer accessories, molding products, etc. The company was about to lunch a new product. Production Manager Nhu asked her assistant, Trinh, to check the capability of a machinery used in the process. Trinh obtained 20 random samples of 16 pieces each. The results of those samples are shown in the following table. After she analyzed the data, she concluded that the process was capable based on a specification width of 1.56 cm. Nhu was quite disappointed when she heard this. She had hoped that with the introduction of the new product her operation could run close to full capacity…

Consider a screening system that analyzes the luggage that is being loadedto a plane. Each package first goes through a screening device. If it passes the test there, then it is loaded to the plane. If it does not, the package goes to a second screening device. The procedure is similar for the second device: if the luggage passes the test, it is loaded to the plane, if it fails, it issent to a third device. Packages that passes the test at third device are loladed to the plane, the ones that fail are taken paprt and not loaded to the plane.The screening devices i = 1; 2; 3 are not perfect. For each device, there are two risks:– With probability pi, each device erroneously passes a bag that is dangerous, given that previous devices have correctly rejected the bag.– With probability qi, each device erroneously fails a harmless bag that previous devices have also erroneously failed.Assume that pi; qi > 0 What is the probability that a dangerous package will be loaded to the aircraft?…
The rabies vaccine for dogs can save your dog's life. If your dog bites another animal or is on the receiving end of a bite, the vaccine can protect them from a dangerous and potentially fatal illness. Furthermore, in most places, the rabies vaccine for dogs is legally required. The NYC Department of Health wants to know if LESS than 95% of the dogs in the city have been vaccinated with their rabies vaccine. 158,045 of the 165,000 dogs examined had their rabies shots. Risk no more than 5% Type I error. Do you retain or reject the null hypothesis? Retain the null. Reject the null.
