For the following problems: a) Identify the null and alternative hypothesis. b) Calculate the critical value c) Calculate the test statistic d) Draw your conclusion on whether the null hypothesis will be rejected or failed to be rejected. e) Find the 95% Confidence Interval According to work done by Nick Wilson of Otago University Wellington, the proportion of individuals who cover their mouths when sneezing is 0.733. As part of a school project, Mary decides to confirm this by observing 100 randomly selected individuals sneeze and finds that 78 covered their mouth when sneezing. Test to see if there is a difference in proportions of people covering their mouth when sneezing. Let a=0.05.

After reporting the results from a formal hypothesis test, it is often likely that statisticians will report a confidence interval in order to indicate that a null value is present, indicating a significant response . True False
2) A researcher is deciding between a sample size of n=250 and a sample of size n=500. Compared to using a sample size of n=500, a 95% confidence interval based on a sample size of n=250 will be * A) narrower and would involve a larger risk of being incorrect. B) wider and would involve a smaller risk of being incorrect. C) wider and would involve a larger risk of being incorrect. D) wider and would involve the same risk of being incorrect. E) narrower and would have the same risk of being incorrect.
In describing the findings of a 2010 Public ReligionResearch Institute poll, the researchers reported a 3%margin of error at a 95% confidence level. If instead theyhad used a 99% confidence level, their margin of errorwould have been:A) still 3%, because the same sample is used.B) more than 3%, because they reported greaterconfidence.C) less than 3%, because they reported greaterconfidence.D) more than 3%, because this sample is too small.E) less than 3%, because this sample is too small.
In a situation where the sample size was decreased from 39 to 29 in a normally distributed data set, what would be the impact on the confidence interval?
An epidemiologist is worried about the prevalence of the flu in East Vancouver and the potential shortage of vaccines for the area. She will need to provide a recommendation for how to allocate the vaccines appropriately across the city. She takes a simple random sample of 332 people living in East Vancouver and finds that 31 have recently had the flu. Suppose that the epidemiologist wants to re-estimate the population proportion and wishes for her 95% confidence interval to have a margin of error no larger than 0.03. How large a sample should she take to achieve this? Please carry answers to at least six decimal places in intermediate steps.
