What is the symbol used for population standard deviation?

What is the symbol used for population variance (i.e. standard deviation squared)?

What is the symbol used for sample mean?

What is the symbol used for sample standard deviation?

What are the steps to calculating the mean and standard deviation from a list of numbers on the TI-84/TI-83?

• Go to STAT then Edit, enter list, then 1-Var Stats

• Go to STAT then TESTS then choose interval

• Go to DISTR then choose normcdf()

• You can do that!?

What are the steps to calculate probability from a binomial distribution on the TI-84/TI-83?

• Go to STAT then Edit

• Go to STAT then TESTS then choose interval

• Go to DISTR then choose binompdf()

• You can do that!?

What is the set of all possible outcomes of a probability experiment?

• an outcome

• the sample space

• events

• a Venn diagram

What type of probability uses a knowledge of sample spaces as opposed to experiments to determine the numerical probability that an event will occur?

• classical probability

• empirical probability

• conditional probability

• subjective probability
