I am interested in the proportion of American taxpayers that file their own taxes each year and so I chose option two to estimate the population proportion. A sample of 1,200 taxpayers was taken from a large population and 453 taxpayers filed their own taxes. Find the 95% confidence interval for the proportion of taxpayer’s that filed their own taxes.

The national council onsmall buisnesses is interested i the proportion of small buisnesses that declared Chapter 11 bankruptcy last year. Since there are so many small buisnesses, the national council intends to estimate the proportion from a random sample. Let p be the proportion of small buisjesses that declared chapter 11 bankruptcy last year. (a) If no preliminary sample is taken to estimate p, how large a sample is necessary to be 95% sure that a point estimate p^ will...

490/654 Venezuelan women from the armed forces said they were not interested in American Football. A 95% confidence interval for the proportion with no interest in American Football is 0.70 to 0.80. A) What would margin of error be for the CI of this proportion? Wouldn't this just be 10%? B) We then sampled 1568 more Venezuelan woman. They were also asked if they had interest in American Football. If we constructed another CI based on this sample, how would...

1. A university Dean is interested in determining the proportion of students who receive some sort 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. By hand, and using formulas for the “Margin of Error” (i.e. not calculator confidence interval), find a 98% confidence interval to estimate the true proportion of students on financial aid. (Use 3 decimal places for proportions.) 2....

You are interested in interviewing people who own both a cat and a dog. The estimated incidence rate in the population is 17%. You expect a survey completion rate of 45%. What final sample size would be required to obtain a statistical estimate of a parameter with an expected proportion of 50% within +/- 3% with 95% confidence? What initial sample size (e.g., how many invites) is required to obtain the necessary final sample size for analysis?
