How do you solve this?I think you use dpois(x,lambda) 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.iv) 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?Type the line(s) of R code that you used to obtain the probability of randomly selecting 3,000 BritishColumbia doctors and finding fewer than seven serious actions taken.

Solution: Let X be the random variable that the number of serious actions taken per 1000 doctors.…

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.
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?
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?
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?
A fleet of 100 taxis is divided into two groups of 50 cars each to see whether premium gasoline reduces maintenance costs. Premium unleaded fuel is used in group A, while regular unleaded fuel is used in group B. The total maintenance cost for each vehicle during a one-year period is recorded. Premium fuel will be used if it is shown to reduce maintenance costs.
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?
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?
A quality control specialist took a 20-sized random sample from a 100-sized batch and analyzed it and adopted a double-tier sampling scheme as follows: If all units in the studied sample are accurate, the batch will be accepted. If the total number of defects in the sample is more than 2, the party will be rejected. If the number of defects in the analyzed sample is 1 or 2, the goods from the first sample are removed from the lot without returning them back to the lot.A second sample with a size of 15 is chosen. If the total number of defects in the first and second samples examined is 2 or less than 2, the party will be accepted, in the other case the party will be rejected. Using the hypergeometric distribution for acceptable quality level (AQL) 0.05 according to the given double-layer sampling plan; a. Find the probability that the batch is rejected after the first sample.b. Calculate the producer risk.
Among college students, the proportion p who say they’re interested in their congressional district’s election results has traditionally been 65% . After a series of debates on campuses, a political scientist claims that the proportion of college students who say they’re interested in their district’s election results is more than 65% . A poll is commissioned, and 194 out of a random sample of 275 college students say they’re interested in their district’s election results. Is there enough evidence to support the political scientist's claim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.) (a) State the null hypothesis H0 and the alternative hypothesis H1 . H0: H1: (b) Determine the type of test statistic to use. ▼(Choose one) (c) Find the value of the test statistic. (Round…
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…
