A laboratory is processing a vaccine, five methods are being tested to determine which is least likely to contaminate the vaccine. If contamination rates were uniform, 20 contaminated vaccines per day would be expected for each method. However, the contaminated vaccines by method are 34, 17, 14, 12, and 23, respectively. Is there evidence to affirm that the rates are uniform?

SOLVE STEP BY STEP IN DIGITAL FORMAT XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 8. If the daily production of a factory machine has more than 10% defective items, it is necessary to repair it. A random sample of 100 parts from the day's production contains 15 defective parts, and the supervisor decides that the machine needs to be repaired. Does the sample evidence support your decision? Use a test with level 0.01
This is an Epidemiology problem. Cataracts of the eye may be difficult to diagnose in the early stages. In a study to evaluate the reliability of their diagnoses, two physicians each examined the same 1,000 eyes, without knowing the other’s diagnoses. Each physician found 100 eyes with cataracts. Does this mean that the diagnoses are reliable? Explain your position.
A certain virus affects 0.7% of the population. A test used to detect the virus in a person is positive 87% of the time if the person has the virus (true positive) and 14% of the time if the person does not have the virus (false positive). Fill out the remainder of the following table and use it to answer the two questions below based on a total sample of 100,000 people. Virus No Virus TotalPositive Test Negative Test Total 100,000a) Find the probability that a person has the virus given that they have tested positive. Round your answer to the nearest hundredth of a percent and do not include a percent sign. % b) Find the probability that a person does not have the virus given that they test negative. Round your answer to the nearest hundredth of a percent and do not include a percent sign. %
You may need to use the appropriate appendix table or technology to answer this question. The average length of time that workers at a certain company remain in their positions has historically been 39 months. Recently, the company has been working to increase the length of time that employees stay in their positions even further. In order to determine whether there has been an increase in the average length of time in the position, a sample of 64 employees was selected. The average length of time in the position in the sample was 45 months with a standard deviation of 16 months. Let 0.05. (a) State the null and the alternative hypotheses (in months). (Enter t for as needed.) H (b) Compute the test statistic. (c) Using the p-value approach, test to determine whether onot the mean length time in the position for all employees at the company is significantly more than 39 months Find the p-value. (Round your answer to four decimal places.) p-value State your condusion Do not reject H…
There's a new treatment for addiction and because resources are limited, a program decides it can offer it only to those people whose ASI scores are in the top 10% of scores. What raw score on the ASI would a person have to have to be eligible for the program?
A state fisheries commission wants to estimate the number of bass caught in a given lake during a season in order to restock the lake with the appropriate number of young fish. The commission could get a fairly accurate assessment of the seasonal catch by extensive "netting sweeps" of the lake before and after a season, but this technique is much too expensive to be done routinely. Therefore, the commission samples a number of lakes and record the seasonal catch (thousands of bass per square mile of lake area) and size of lake (square miles). A simple linear regression was performed and the following R output obtained. Estimate Std. Error t value Pr(>|t|) (Intercept) 2.5463 0.4427 5.7513 0.0000 size 0.0667 0.3672 0.1818 0.8578 The residual plot is below.

Burning fuels in power plants and motor vehicles emits carbon dioxide (CO2), which contributes to global warming. The CO2 emissions (metric tons per capita) for countries varies from 0.02 in Burundi to 44.02 in Qatar. Although the data set includes 214 countries, the CO2 emissions of 15 countries are not available on the World Bank database. The data set is too large to display but the data for the first five countries is given. Use the full data set with data on the 214 countries to answer the questions.
