- Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data setsfor which such a procedure is not appropriate. Use calculators, spreadsheets, and tablesto estimate areas under the normal curve.
- 6. Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.
- Understand statistics as a processfor making inferences about population parameters based on a random sample from that population.
- Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.
- Use data from a randomized experiment to compare two treatments; use simulations to decide if differences between parameters are significant.
- . Evaluate reports based on data
- Describe events as subsets of a sample space (the set of outcomes) using characteristics(or categories) of the outcomes, or as unions, intersections, or complements of other events (“or,” “and,” “not”).
