Please answer all parts. Will rate, Thank you. A meat processing plant has 240 workers. 40 of them work in administration, while the remaining works on the shop floor. 80% of the people working on the shop floor use knives to cut whole animals into smaller pieces and to debone, putting them especially at risk of carpal tunnel syndrome (CTS). 75% of the shop people using knives have CTS, while 85% of the shopworkers who don’t use knives have no problems. 45% of the people working in the administration do a lot of computer work, putting them at risk of CTS as well, and 3 of them have CTS, while none of the others working in administration has CTS. Create appropriate tables and use them to calculate the following: a. Calculate the odds ratio of CTS for shop workers only b. Calculate the relative risk of CTS for shop workers only c. Calculate the odds ratio of CTS for all workers d. Calculate the relative risk of CTS for all workers

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.

According to an article in Newsweek, the natural ratio of girls to boys is 100:105. In China, the birth ratio is 100:114 (46.7% girls). Suppose you don't believe the reported figures of the percent of girls born in China. You conduct a study. In this study, you count the number of girls and boys born in 150 randomly chosen recent births. There are 64 girls and 86 boys born of the 150. Based on your study, do you believe that the percent of girls born in China is 46.7? Conduct a hypothesis test at the 5% level.Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)State the distribution to use for the test. (Round your standard deviation to four decimal places.)P' ~ What is the test statistic?

According to an article in Newsweek, the natural ratio of girls to boys is 100:105 . In China, the birth ratio is 100:116 ( 46.3% girls). Suppose you don’t believe the reported figures of the percent of girls born in China. You conduct a study. In this study, you count the number of girls and boys born in 100 randomly chosen recent births. There are 42 girls and 58 boys born of the 100 . Based on your study, do you believe that the percent of girls born in China is 46.3 ? A.)What is the test statistic? Round your answer to three decimal places. (z / t ) = B.) What is the p -value? Round your answers to four decimal places. p -value = C.) Let α=0.05 . Decision: (Reject the null hypothesis / do not reject the null hypothesis) Reason for decision: ( a < p-value / a > p-value) Conclusion: There is (insufficient/ insufficient) evidence to conclude that the percentage of girls born in China is different from 46.3% .
