Healthcare workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. Symptoms of a latex allergy include conjunctivitis, hand eczema, nasal congestion, a skin rash, and shortness of breath. Each in a sample of 46 hospital employees who were diagnosed with latex allergy based on a skin-prick test reported on their exposure to latex gloves (Current Allergy & Clinical Immunology, March, 2004).Summary statistics for a number of latex gloves used per week are = 19.3 and s = 11.9. A) Form a 95% confidence interval for the average number of latex gloves used per week by all health care workers with a latex allergy. B) Form a 90% confidence interval for the average number of latex gloves used per week by all health care workers with a latex allergy. Please show step by step and formula used.
A research team is hired to investigate the prevalence of periodontal disease in a rural countywith a low average socio-economic status. The team is given the task of surveying the area, andproviding a brief examination of participants to correctly identify cases of periodontal diseaseand estimate an overall prevalence. If the team identifies an overall prevalence of above 25%, thesponsoring organization is to initiate an active campaign promoting healthy dental practice. Outof 2,879 participants surveyed, 589 were identified to have periodontal disease. A) Conduct a formal test for detecting if the prevalence of periodontal disease in the sample issignificantly different from the minimum prevalence for intervention. Use an alpha level of 0.01.B) Interpret your conclusions.
A company that sponsors LSAT prep courses would like to be able to claim that their courses improve scores. To test this, they take a sample of 20 people, have each take an initial diagnostic test, then take the prep course, and then take a post-test after the course. The test results are below (scores are out of 100%): Person1234567891011121314151617181920Initial Test7368707979606880637865687367606277647069Post-Test7075767493566987778170817377637578706766 Is there evidence, at an α=0.01α=0.01 level of significance, to conclude that the prep course improves scores? Carry out a Wilcoxon signed rank test, filling in the information requested. (Arrange your data so that the standardized test statistic is for the change from the initial test to the post-test.)

The Los Angeles City Controller's office calculated that in 2013, the city employed 4703047030 full‑time employees and 1014210142 part‑time employees. Assume that an outside advocacy group had been lobbying the Mayor's office to convert part‑time workers into full‑time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per‑event employees) who are full‑time employees ?p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per‑event employees) in June 2014 and found that 845845 were full‑time employees and 155155 were part‑time employees. If the advocacy group planned to use a one‑sample z-z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would be Assume…
A group committed to quality television has been concerned about a new talk show. For two weeks, they decide to count the number of words that must be "bleeped" as too obscene for television and the number of physical altercations. They hope that after recording this data that they will be able to argue that the show is inappropriate for television particularly during the day. The data for number of words censored is provided below. 34226732115733349254166132289 a) Find the variance and standard deviation.b) What does this information tell you about variability of number of words censored per show?
The personnel director of the Target Corporation wants to estimate the number of employees within one year of retirement. A simple random sample of 80 employees' records is selected, and four people are found to be within one year of retirement. Formulate a 98% interval estimate for the true proportion of employees within one year of retirement in the entire corporation.

In a survey, it was found that consuming fruit juices is not as healthy as consuming fruit. It is believed that fruit juices contain artificial flavors and preservatives (Source: http://www.fda.gov/food/guidanceregulation/guidancedocumentsregulatoryinformation/labelingnutrition/ucm064880.htm). Assume that in a survey to assess whether or not people believe fruit juices contain artificial flavor, 53% believed that fruit juices contain artificial flavors. In a random sample survey of 100, construct a 95% confidence interval for the population proportion who believe that fruit juices contain artificial flavors. Do the results indicate that the majority of the population believes that they contain artificial flavors? Now modify the sample from 100 to3,600, construct a 95% confidence interval for the population proportion that believes that fruit juices contain artificial flavors. What do the results indicate now?
According to the February 2008 Federal Trade Commission report on consumerfraud and identity theft, 23% of all complaints in 2007 were for identity theft. Inthat year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumercomplaints ("Consumer fraud and," 2008). Does this data provide enoughevidence to show that Arkansas had a higher proportion of identity theft than23%? Test at the 5% level.
A company studied the number of lost-time accidents occurring at its brownsville,Texas, plant. historical records show that 6% of the employees suffered lost-time accidents last year.

In addition, it estimates that 15% of employeeswho had lost-time accidents last year will experience a lost-time accident during thecurrent year.a. What percentage of the employees will experience lost-time accidents in bothyears?
