A recent study by the Center for Disease Control claims that a new super-contagious virus will impact a population in which it is found if left unchecked. A recent occurrence of this virus happened on an very isolated island nation with over 30,000 inhabitants. In randomly testing 400 residents of this island after the virus outbreak, a research team found 330 tested positive for having been infected by the virus.
A. Describe the possible Type I error for this situation--make sure to state the error in terms of the percentage of a population infected by the virus.
B. Describe the possible Type II error for this situation--make sure to state make sure to state the error in terms of the percentage of a population infected by the virus.
C.Determine the appropriate critical value(s) for this situation given a 5% significance level.
D. Determine/calculate the value of the sample's test statistic.
E. Determine the P-value.
F. Based upon your work above, should you "Reject the null hypothesis" or "Fail to reject the null hypothesis?" Explain why.
G. Based upon the work above (and assuming requirements of the hypothesis tests are met), is there statistically sufficient evidence in this sample to support the claim that the percentage of a population that will be infected by the virus if left unchecked will be over 80%? Explain your reasoning.

8. A random sample of 25 college males was obtained and each was
asked to report their actual height and what they wished as their
ideal height. A 95% confidence interval for μd= average difference
between their ideal and actual heights was 0.8" to 2.2". Based on
this interval, which one of the null hypotheses below (versus a
two-sided alternative)can be rejected?
A. H0: μd= 0.5
B. H0: μd= 1.0
C. H0: μd= 1.5
D. H0: μd= 2.0

The z-test 10.1 Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests,...

Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and population, you can use it in your model the next time there is an cpidemic, thus cnabling you to make predictions about the demand...

Research is an integral part of all professional fields. Designing a research study can be a complicated task that can be simplified if the appropriate techniques can be identified. This assignment will give you the opportunity to design an experiment, including finding relevant prior research, determining the appropriate sample, data analysis techniques, and discuss the results you hope to see. Working from the topic chosen earlier in the topic selection, you will be designing your own statistical study. In a...
