Suppose that 60% of Americans planned to vote in the next election. You take a random sample of 100 people and ask them if they plan on voting in the next presidential election.  What approximate distribution would you expect for the sampling distribution of the sample proportion of Americans who planned on voting?

Suppose that you took a random sample of 25 students at FSU and asked them how many minutes they exercised yesterday. Suppose that you wanted to make a 99% confidence interval for the population mean. What value would you use for t?

Suppose that you were interested in conducting a survey of Floridians and asking if they approved of the President. Suppose that you have no idea what this proportion would be, but at the end of the study you want to calculate a 95% confidence interval with a 0.045 margin of error. Find the sample size needed.

Suppose the sampling distribution for average calories in bananas is normally distributed with a mean of 105 and a standard error of 4.  Find the range of central 99.7% of sample means.

Which of the following is a property of the t distribution?

Besides random sampling, what conditions are necessary for the sampling distribution of the sample proportion to be approximately Normally distributed? (There may be more than one answer. Please check all that apply.)

Suppose that you were going to take a sample of UF students. You were interested in estimating the proportion who had at least one non-related roommate. You were uncertain what this proportion was; however, you wanted to be 95% confident with a margin of error equal to 0.034. What sample size do you need?

For Ho:p = 0.60 versus Ha: p does not equal 0.60, when the test statistic equals 1.54, what is the p-value?

In the year 2014, according to salary.com, physical therapists in Jacksonville, Florida have an average annual salary of 75,000. The standard deviation is about 6,000 dollars. Suppose that a sample of 15 physical therapists is taken from Jacksonville, Florida. What is the sampling distribution of the sample mean?  

In the 2012 presidential election, 57.5% of eligible voters cast their vote. Suppose that 200 randomly selected eligible voters were asked if they had voted in the 2012 presidential election. What approximate distribution would you expect for the sampling distribution of the sample proportion of Americans who voted in the 2012 presidential election?
