How do you solve this? The Public Citizen's Health Research Group studied the serious disciplinary actions that were taken during arecent year on nonfederal medical doctors in the U.S. The American average was 3.84 serious actions per1,000 doctors. Assume that the Canadian average is the same; moreover, assume that the number of seriousactions per 1,000 doctors is Poisson distributed.iii) Assume that British Columbia has an average of 1.6 serious actions per 1,000 doctors. What is theprobability of randomly selecting 3,000 British Columbia doctors and finding fewer than seven serious actionstaken?Your final answer must be a number. Please round it to 4 decimal places. Thanks!

You work with the office of city planning which is currently evaluating a new contract for a major highway. The chosen contractor claims that the roads they build usually have a single (1) defect per 50 miles of road, assume this follows a Poisson distribution. The portion of the highway that your city is building is 30 miles long. Within the contract there is a clause which states that if 5 or more defects are found in the completed project then the contractor must reimburse a third of the final payment. What is the probability that this happens?
And a pool, 102 of 1020 randomly selected adults age 18 or older stated that they believe there is too little spending of national defense. Obtain a point estimate for the proportion of adults age 18 or older who filled there is too little spending on national defense.
From the study on work sampling, it was found that a group of machines - consisting of 4 machines - were operated by operators, it was noted that 65% of machines could be operated without the need for operators to attend and 35% of operators would be present to carry out loading / unloading, maintenance activities , and / or other machine service activities. Furthermore, what is the estimated machine hours that will be lost per 8 hours of work due to "scarcity" of operators?
In order to compare the real estate markets in Pittsburgh and Philadelphia, a realtor selected a random sample of 150 homes in the Pittsburgh area and 100 homes in the Philadelphia area. Shown below are dotplots showing the distribution of home price for the homes in these two cities.
Suppose that 77% of the students at a small private university carry student loans. For a SRS of students at this university, let P(hat) be the sample proportion of the students who carry student loans. How large would a sample from this population need to be to ensure that the distribution of the sample proportion is normally distributed?
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 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. Management believes that a special safety program will reduce suchaccidents to 5% during the current 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?
Of the 200 randomly selected local fishers, 28 are solely fishing as income source and 172 have alternative or supplemental livelihood such as getting employed as a construction worker, farmer, carpenter, motorcycle/tricycle driver, selling/vending souvenir and other products, or working in a passenger boat batil or tripolante (i.e., captain or crew). Their estimated monthly income (in PhP) are shown below. Using α = 0.05, is there a significant difference in the monthly income of fishers whose sole livelihood is fishing compared to those with alternative/supplemental income sources? Assume that the fishers income is normally distributed a) Analyze manually b) Analyse using SPSS
A university dean is interested in determining the proportion of students who recieve some sor of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. If the dean wanted to estimate the proportion of all students receiving financial aid to within 4% with 90% reliabilty, how many students would need to be sampled?
Suppose that 97% of Monarch butterflies migrate to Mexico in winter. What is the smallest sample size required to ensure that the sample proportion is Normally distributed?
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.
The National Center for Education Statistics reported that 47% of college students work to pay for tuition and living expenses. Assume that a sample of 450 college students was used in the study.
