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?

The Queensland male koala has an average weight of 6.5kg. Male Koalas weights are normally distributed with a standard deviation of 0.82. Suppose that 10 randomly selected koalas were selected. What is the sampling distribution of the sample mean?

Suppose that you were going to take a sample of Florida students. You were interested in estimating the proportion who had ever called/emailed/spoken with their congressmen. You were uncertain what this proportion was; however, you wanted to be 95% confident with a margin of error equal to 0.028. What sample size do you need?

In the Congo, the infant mortality rate is 5.934%. Suppose that a random sample of 1000  births was conducted. What is the probability that the infant mortality rate in the sample was less than 5.7%?

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 Queensland male koala has an average weight of 6.5kg. Male Koalas weights are normally distributed with a standard deviation of 0.82. Suppose that 5 randomly selected koalas were selected. What is the sampling distribution of the sample mean?

Find the value of t for a 90% confidence interval for the population mean when n = 19.

The average height of men in Cameroon is 1.706 meters with a standard deviation of 0.154 m. Height is approximately normally distributed. Suppose that a sample of 35 men is selected, find the range of the central 68% of sample mean heights?

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 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?
