Suppose that 60% of Americans planned to vote in the next election. You take a random sample of 60 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?

The amount of calories in a small serving of French Fries at McDonalds is Normally distributed with a mean of 230 calories and a standard deviation of 15. Suppose that a random sample of 12 small servings was collected. What is the probability that the sample mean is greater than 240 calories?

A pollster was interested in testing the hypothesis to see if there was majority support for a certain political candidate. She found a p-value equal to 0.005. What would be her conclusion?

Suppose the sampling distribution for average height for soccer players is normally distributed with a mean of 71.5 and a standard error of 2 inches.  Find the range of central 68% of sample means.

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.)

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 took a random sample of 15 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?

For Ho:p = 0.60 versus Ha: p does not equal 0.60, when the test statistic equals 1.44, what is the p-value?

Forty two males were recorded on their reaction time to a stimulus. The 95% confidence interval for the population mean was (17.10, 20.34) seconds. What do we know from this confidence interval?
