State Standards:
- S.IC.A.1 Recognize the purposes of and differences among sample surveys, experiments, and observational studies, explain how randomization relates to each.
- S.ID.A.1 Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages using the Empirical Rule
- S.IC.A.2 Use data from a sample survey to estimate a population mean or proportion; use a given margin of error to solve a problem in context.
